Thank you very much for joining me this evening. You can reflect on tonight's events with our match report and reaction on the Sky Sports website. You can keep in touch with me via @BH92. Once again, thanks for joining me.
I think the man-of-the-match accolade has to go to Toni Kroos. The enigmatic midfielder posed a constant threat to the Arsenal defence, his passing statistics were peerless and a goal to boot.
It's all over at the Emirates Stadium. Just like last year, Bayern Munich leave North London with a two-goal lead. Goals from Toni Kroos and Thomas Muller. Full time in this last-16 first leg, Arsenal 0-2 Bayern Munich.
Bayern take a short corner and Gotze strikes from distance. Arsenal on the racks here. Full time cannot come quick enough!
Pizarro could have really turned the screw as he found space in the box before running out of touch.
GOAL! THOMAS MULLER! Three minutes from time, Arsenal are breached again. The German striker heads home the elusive second after making a fine run to meet Lahm's cross from the right.
Koscielny wins a free-kick for Arsenal on the halfway line, much to the delight of the Emirates faithful. The set-piece is wasted by Arsenal and Bayern launch the counter attack.
Alaba takes the free-kick short and Bayern look to pass their way into the Arsenal box, unsuccessfully.
More one-way traffic as Bayern nonchalantly make their way into Arsenal territory before Tomas Rosicky is booked for running into Kroos.
A rare charge from Arsenal is quickly broken down by a composed Neuer, who no matter how unused, always remains confident. He has been brilliant tonight, although called on little.
Bayern unable to use their set-piece but again they come at Arsenal, who must be applauded for their effort, there has been a lot of chasing!
Robben dances his way into the Arsenal box and wins a corner for the visitors. Arsenal cannot afford to switch off for a second here.
Gotze brings it down the left before cutting inside to cross to the back post, where Fabianski collects with ease.
Pep Guardiola definitely chasing a second, maybe even more, goals to try and put the tie to bed early.
Bayern passing around with plenty of panache and zest, while Arsenal look laboured as they try and close the visitors down.
It's starting to look like a training ground exercise for Bayern as Muller races into the box, where Koscielny trips the striker and is lucky to not give away a second penalty.
Robben finds Lahm on the overlap, the Bayern skipper crosses low towards Kroos, whose header ricochets off Mertesacker for a corner.
Arsenal briefly regain possession but all Sagna can do is launch the ball into Bayern territory and back the hosts come.
More interplay between Gotze and Alaba on the left before the former picks out Robben on the right. The Dutch winger switches to his left foot and curls just wide of Fabianski's post.
Gotze attacks the left flank this time and cuts back in to Lahm, who is unable to pick out Muller in the box.
The aforementioned build-up play led to Rafinha finding space on the right, he squared the ball into Muller, who came agonisingly close to getting a touch, which would surely have doubled Bayern's lead.
Arsenal being given a masterclass in ball retention here as Bayern show off their silky build-up play.
Wilshere draws a free-kick from Lahm on the halfway line but Bayern quickly regain possession and look to made inroads once again.
Bayern's top scorer Mario Mandzukic is replaced by Thomas Muller, who is only one goal behind his teammate with 17 this season.
Bayern close to doubling their tally as Robben breaks free but he is unsure whether to go alone - which he does in the end - or utilise Mandzukic at the back post. Shot saved easily by Fabianski.
Arsenal swing the cross towards the back post, where it collected by Neuer. Arsenal are appealing for a corner but the referee and his assistants are not interested.
Monreal chases a loose ball in the Bayern half and Martinez has no option but to bring the defender down.
Robben cutting inside again before Bayern simply pass their way around the edge of the Arsenal box. They're toying with the hosts here.
'Ole' cheers ring around the Emirates from the 3,000 Bayern fans as their side pass with ease in the final third.
Robben looks to slide Rafinha in on the right but Monreal steps in to intercepts from the full-back.
The question now for Arsenal is can they stay in the tie ahead of the second leg. Bayern look to threat from the corner as Alaba and Lahm link up on the edge of the box.
GOAL! TONI KROOS! SENSATIONAL strike from Toni Kroos! Lahm with a simple lay-back to the German midfielder and he strikes with venom beyond Fabianski, who ends up in the back of his own net. What a goal!
Robben cuts back in from the right onto his favoured left foot and lines up another shot from the edge of the box. Fabianski has a clear view and is more than equal to the attempt.
More problems down the right for Arsenal as Rafinha gets the better of Ozil and Monreal before wasting possession.
Arsenal awarded a free-kick just inside Bayern territory. Ozil floats it forward and Koscielny, of all people, makes a run into space before being forced wide.
Lahm, now operating as a midfield general, picks out Alaba on the left before Kroos launches a cross-field ball to Rafinha, who was allowed to run free by Ozil.
Alaba squares the ball from the left but, somehow, misses both Kroos and Mandzukic in the centre. The danger is not clear for Arsenal but Gotze strikes it straight into the hands of Fabianski.
Bayern direct the corner towards Mandzukic, who once again is unable to win the aerial duel in front of goal.
Lahm spreads the ball wide for Robben, who is still being booed by the Arsenal crowd. Rafinha comes at Monreal on the right and wins a corner for the visitors.
The European champions get us back underway...Let's hope we see a more productive display in front of goal from both sides.
Players are back on the field and Bayern make a change at the break. Rafinha comes on for Jerome Boateng, who was booked in the first half.
@Blondiee on Twitter says: "Arsenal better win...I think they might put my mum into early labour playing like this haha :)) #COYG"
Ben David says: "Come on Arsenal show that resilience and mental strength you been showing us all season in Arsenal I believe"
What can we expect from the second half? How do Arsenal survive with 10 men against Bayern Munich? Get in touch with your views... You can find me on Twitter, @BH92, or you can email me, Benjamin.Hampshire@bskyb.com.
No goals but no shortage of drama in the first half! Arsenal should have taken the lead early on but Mesut Ozil missed from the penalty spot. The Gunners were then reduced to 10 men when goalkeeper Wojciech Szczesny was shown a straight red for bringing Arjen Robben down in the box. And, unbelievably, David Alaba missed the subsequent spot-kick. As it stands, we remains goalless, Arsenal 0-0 Bayern Munich.
No real gusto shown from Bayern in the final minute of the half as they pas their way across the halfway line before the referee brings the opening period to a close.
Two minutes added time to be played. Mario Mandzukic goes into the referee's book after an altercation in the Arsenal area.
Boos echo around the Emirates as Robben picks up the ball as Bayern just pass their way around Arsenal territory.
Neat link-up between Sanogo and Wilshere is broken down by Kroos, who gets a quick talking to from the referee.
Lahm and Robben in full flow down the right-hand side but Arsenal remain resilient. Can they hold out to half time?
MISSED! Two missed penalties in 40 minutes! Alaba cannot believe it as his spot-kick scrapes the outside of the post. Unbelievable!
Confirmation of that red card for Wojciech Szczesny, who went to ground when he really should have stayed on his feet.
Bayern definitely ganging up on Arsenal down the right and Robben exchanges with Kroos, who chips into the path of his teammate. Robben skips round Szczeny, who clips the Bayern striker and sees red! Penalty to Bayern, will they take their chance?
Not sure Monreal is as Robben slides a precision ball through to Mandzukic but the Croatian striker is caught in possession.
Danger is not clear for Arsenal however, as Alaba attacks the left flank before running out of touch.
Sagna's loose pass falls straight into the path of Gotze but Mandzukic was caught napping and Arsenal get away with it.
Lahm threads a ball into Robben, who beats Monreal, before realising he has no support in the box and goes backwards.
Gibbs' departure does not fluster Arsenal as they resume their attack down the right with Oxlade-Chamberlain, but his low cross goes straight into the hands of Neuer.
The visitors loitering around the Arsenal box with intent but they lose possession and concede a free-kick when Boateng trips Wilshere in pursuit of a loose ball.
Free-kick for Bayern, midway into Arsenal territory, after Ozil just leans into Thiago. Kroos swings it towards the back post but Mandzukic in unable to steer his header on target.
Threatening move from Bayern, started on the right with Lahm once more, but Mandzukic is closed down by some composed work from Koscielny and Sagna.
Arsenal's corner is directed towards Sanogo but he is unable to get the ball under control and Robben starts the Bayern counter attack.
Again, Oxlade-Chamberlain jinks his way down the right wing and wins a corner for Arsenal. At this time last year, Arsenal were two down, can they take the lead here...
Lofted ball through the middle from Sanogo for Oxlade-Chamberlain but he loses the foot race against Neuer, who launches the ball into clear. It was close, another inch of pace and 'The Ox' could have put Arsenal ahead.
Bayern come straight back at Arsenal with Kroos and Alaba but the hosts press high and win possession back.
Thiago is starting to conduct the midfield battle. He finds Lahm, who crosses towards Alaba at the back post but Arsenal head the ball clear, for now.
Arsenal's one-touch play around the area once again coming to the fore but it breaks down when Sanogo is unable to re-find Ozil. Carzola does manage to get a shot away in the end but it goes straight into the hands of Neuer.
Bayern enjoying the majority of possession now and Arsenal's red-hot start is cooling by the minute as Thiago and Alaba link up on the left.
Kroos' corner looks to have been cleared yet it falls to the feet of Alaba, who hits it with venom, but Carzola is in the way for Arsenal.
Long ball forward from Szczesny goes straight out of play and Bayern attempt to build from the back with Dante.
Lahm is tracking the right wing well, as usual, and slips a neat ball into Gotze. Corner to Bayern is swung towards Martinez, who is unable to guide the ball anywhere near the target. Arsenal goal-kick.
Lahm finds space on the right and puts an inviting cross towards Mandzukic, but Szczesny is out quickly to collect.
After a frantic start which saw Bayern caught on the hop, the tempo is settling nicely, which will suit the visitors much better.
Boateng attempts to a slide a ball into the path of Lahm on the right wing but Carzola steps in to intercept but the counter attack soon fizzles out.
Free-kick in a good position - about 30 yards out - for Bayern but Robben is unable to get his shot over Metersacker in the Arsenal wall.
That penalty miss has had a clear impact on the stadium atmosphere and Bayern are look to settle the pace of play down.
MISSED! Ozil - a childhood friend of Neuer - is denied by his compatriot. A second Champions League penalty miss for Ozil this term. Far too nonchalant!
Arsenal slide the ball through to Ozil and he is clipped by Boateng, he left his foot out. Lazy defending and no arguments at this level.
Lahm is disposed and Arsenal race forward, with Oxlade-Chamberlain putting the cross in towards Sanogo, who is unable to win the header. The ball falls for him a second time however and the Champions League debutant fires at Neuer, who is forced into action.
The Gunners find Sanogo from the set-piece but the 20-year-old looks a bit flustered as he watches the ball run out of play.
Arsenal win a free-kick just inside the Bayern half after Dante caught Wilshere, who made a bit of a meal of the contact.
Bayern's subsequent corner is cleared by Arsenal and they launch they counter attack through Ozil, but are soon slowed down by a pressing Munich defence.
CHANCE! Lahm pulls Bayern in from the right wing and Kroos lines up a shot and strikes with ferocious power, forcing a finger-tip save from Szczesny! Excellent attempt from the German forward.
Positive start from Sanogo as he takes the fight to the Bayern defence before running into traffic. The visitors get their first touch with a free-kick on the halfway line.
Early ambition from the in-form Oxlade-Chamberlain as he bursts into the Bayern box after a fine cross-field ball from Carzola.
Referees have been the centre of attention today in the media and the man in charge of tonight's affair is Nicola Rizzoli of Italy.
Bayern Munich starting XI: Manuel Neuer, Philipp Lahm (c), Dante, Jerome Boateng, David Alaba, Javi Martínez, Thiago Alcantara, Mario Mandzukic, Arjen Robben, Mario Götze, Toni Kroos
Arsenal starting XI: Wojciech Szczesny, Bacary Sagna, Per Mertesacker (c), Laurent Koscielny, Kieran Gibbs, Mathieu Flamini, Jack Wilshere, Alex Oxlade-Chamberlain, Santi Carzola, Mesut Ozil, Yaya Sanogo.
As the teams make their way out onto the field, it's a good time to remind ourselves of the starting line-ups...
Luke Baker believes writing off Arsenal is a bad move. "Everyone writing off Arsenal tut tut, the team who have had the best back four all season so far if they can stay strong anything can happen," he says.
Young Thomas Armitage has been in touch. He says: "I'm a nine-year-old Arsenal fan from London and I'm going for 2-1 Arsenal with The Ox and Ozil grabbing goals for Arsenal and Robben getting a late consolation goal for Bayern. #COYG"
@Itslitledan on Twitter believes: "Bayern will win 3-0. I believe both legs will be on Bayern's side."
Bayern fan Niall Ryan says: "Gunners to be floored 3-0 tonight...I've been to Bayern's last two games...it's frightening to think but I reckon their better all round than last season...no team able to match them at the moment...my biggest fear is playing a rematch against Barca...revenge is on the cards."
Bayern Munich have won their last two away games against English teams in the Champions League, both with a 3-1 scoreline (against Arsenal and Manchester City). Another omen going against Arsenal?
Arsenal have lost their last three home games against German clubs in the Champions League (v Schalke and Bayern Munich last season, v Borussia Dortmund this season). Omen?
Chirag Saha says: "I'm a Gunner fan from India. People are writing Arsenal off but even a 0-0 draw will be a good result! COYG!"
This is the third time that Arsenal and Bayern Munich are meeting in the last 16 of the Champions League. The Bavarian club have progressed both times (2004/05 and 2012/13).
Dan Wilson also believes Bayern will take the honours, he says: "No way are Arsenal gonna get anywhere near a result tonight, Bayern will have far too much class, gonna say Bayern to win 3-0."
Jordan Green expects a high-scoring, one-sided affair. "Bayern will win 5 nil!! Arsenal don't have a chance," he claims.
Ben Gleeson is behind the Germans, he says: "I thought before the game that a lot would depend on which attack Pep picked. He's been switching between a false 9 with Gotze, and a proper striker with Mandzukic. I feel Per and Kosc could deal with Gotze, but they will struggle with the brute force and aerial ability of Mandzukic. 1-3 to the Germans."
Bayern have won five straight league matches since returning to action after a winter break and Guardiola recognises that they are favourites to progress, but he is taking nothing for granted in what he expects to be a close tie.
They also set a new competition record of 10 straight Champions League victories by winning their first five group matches this season, before that phenomenal run came to an end when Manchester City hit back from two goals down to win 3-2 in Germany.
There have been no signs of the hunger waning since Guardiola took charge last summer, with Bayern unbeaten in the Bundesliga after winning 19 of their 21 matches to open up an apparently insurmountable 16-point gap.
Arsene Wenger has justified his deicsion to play Sanogo ahead of Giroud. "He's playing well, simple as that," he told Sky Sports in the Emirates tunnel.
Adam Pearson expects the European champions to prevail, he says: "I'm really not understanding the support for Arsenal to win this. Bayern are the best team in Europe and Arsenal have a long way to before the can say the same. I see the Gunners being gunned down."
Elliot Kohn from Suffolk is pleased with Wenger's team selection. "Feeling slightly confident tonight, glad to see Sanogo selected again, we have to give it our all and I'm hoping for a 2-0 win for the Gunners! #COYG"
Dave has been in touch from Weymouth, he expects: "It's gunna be a good night for the Gooners. 2-0. Enjoy."
Ben David claims: "The key to this game is for Arsenal to get a early goal and rattle Bayern, my prediction 2-1 Arsenal."
More predictions now and Muji says: "Can't see Arsenal winning here. Bayern are just too strong. Bayern to win 2-1, but, as an Arsenal fan, I hope I'm wrong."
Bayern bench: Tom Starke, Daniel Van Buyten, Rafinha, Claudio Pizarro, Thomas Muller, Deigo Contento, Bastian Schweinsteiger
Arsenal bench: Lukasz Fabianski, Nacho Monreal, Carl Jenkinson, Tomas Rosicky, Serge Gnabry, Lukas Podolski, Olivier Giroud
Bayern Munich starting XI: Manuel Neuer, Philipp Lahm (c), Dante, Jerome Boateng, David Alaba, Javi Martinez, Thiago Alcantara, Mario Mandzukic, Arjen Robben, Mario Gotze, Toni Kroos
Arsenal starting XI: Wojciech Szczesny, Bacary Sagna, Per Mertesacker, Laurent Koscielny, Kieran Gibbs, Mathieu Flamini, Jack Wilshere, Alex Oxlade-Chamberlain, Santi Carzola, Mesut Ozil, Yaya Sanogo.
Richard in Swansea is also backing the Gunners, he says: "Really hope they win tonight, need a good performance from Ozil, and a clean sheet! 2-0 to the Arsenal!"
Tom Sheridan in Ireland says: "Hoping the Gunners will gain revenge on the European champions for last year's defeat, there's more quality and confidence in the side this year! Going for a 1-0 win to Arsenal! COYG!!!"
However, Arsenal will still be under no illusions as to the size of the task facing them against the European champions, with Bayern looking to underline their status as the continent's dominant force by becoming the first side to win the trophy in two consecutive years.
Memories of a 2-0 away win in last season's second leg are sure to give Arsenal some confidence, while spirits will have been lifted by a 2-1 FA Cup victory over Liverpool at the weekend.
Louis Paddington on Twitter believes Arsenal are going to struggle. "No chance for Arsenal tonight," he said. "I expect the tie to be over by halftime, with Bayern eventually winning 5-0 this evening."
There have been one or two blips along the way, such as a 5-1 thrashing at the hands of Liverpool earlier in February, and midfielder Jack Wilshere has admitted Arsenal must play more intelligently against Bayern than they did last year to ensure the tie is still alive going into the return leg at the Allianz Arena on March 11.
Currently second in the Premier League, just a point behind title rivals Chelsea, and through to the FA Cup quarter-finals, Arsenal are still fighting on three fronts to end their well-documented trophy drought.
Daniel Don Bosco agrees with Wenger, he expects: "Arsenal are going to have revenge on Bayern Munich. 2-0 to Arsenal."
Arsene Wenger insists his side are now in 'much better mental shape', exactly one year on, but Arsenal will regret their failure to again finish top of their group.
The damage was done in North London 12 months ago, too. Bayern scored twice inside the opening 21 minutes as they ran out 3-1 winners.
First prediction of the night comes from Chris Green in Huddersfield. He says: "Tonight the Gunners will need to keep on top of Bayern Munich's attacking prowess, as the current holders of the European Cup have the players who are capable of destroying any defence they face. However, being on home soil gives them every chances of taking a valuable lead back to Germany. Therefore, the Gunners need to make sure that they exploit every opportunity that comes their way. Prediction: Arsenal 1-1 Bayern Munich."
Defending champions Bayern Munich knocked the Gunners out at this stage last term after a 3-3 aggregate draw and are now arguably even stronger, under the tutelage of Pep Guardiola.
Can Arsenal gain revenge for last year's heartache? Or are Bayern simply too strong? Get in touch with your opinions and I will endeavour to publish as many as possible.
