So Arsenal's Champions League adventure is over. Thanks for joining us on the commentary tonight. Report, reaction and more to follow.
Full-time: Bayern Munich 1 (Schweinsteiger 55) Arsenal 1 (Podolski 57). Bayern Munich win 3-1 on aggregate.
PENALTY SAVED! Fabianski saves Muller's effort with his legs, and then recovers to scoop away the loose ball as it rested on the goalline. Still 1-1 on the night.
Gnabry tries a shot but it's high and wide. Arsenal attentions beginning to turn to Sunday's derby clash away to Tottenham now.
Cazorla floats in a cross from the left for Gnabry, but Alaba rises just high enough to nick the ball away with his head.
Strong header from Mandzukic but it's straight into the body of Mertesacker, and a very tired Arsenal manage to get the ball away.
A bold attacking move from Wenger. Arteta was erring close to a second yellow card though, so probably wise.
A low shot from Robben, after coming infield and past Vermaelen at the top of the area, but Fabianski is equal to it.
It's now Atletico Madrid 3 AC Milan 1 on the night, giving the Spanish side a 4-1 aggregate lead and surely a quarter-final berth.
Fabianski is alert and denies Mandzukic at close range. That would have been a well-worked Bayern goal. Schweinsteiger played the ball into the area for Thiago, who knocked it across first time to Mandzukic - but he took a touch too many.
Podolski is penalised for a push on the touchline. Like Arteta, he needs to watch his step after his first-half booking.
After that frenetic few minutes, the tempo has dropped a little. Bayern have regained their composure and are on the attack. Bayern have had 443 passes to Arsenal's 180 in the game so far.
Cazorla's corner comes out to Oxlade-Chamberlain on the edge of the area and he gets a shot on target, but Neuer reaches to his left to grab hold of the ball.
Arsenal look to be in again and Alaba has to clear from under Giroud's feet as the ball comes in from the left.
A one-two between Giroud and Podolski puts the latter in a race with Lahm down the left and although the Arsenal forward looks to have impeded Bayern's skipper, he's allowed to continue and smashes in an equaliser from a tight angle.
A simple goal really. Ribery dribbles casually into the left side of the area, Sagna turns away, and the winger plays a square pass into the middle where Schweinsteiger turns a shot home past Fabianski for his first goal since October. All over for the Gunners now, you'd think.
Replays suggest there was contact between the feet of Cazorla and Robben in the area, but did the Dutchman need to go to ground? He didn't look off balance. That was the referee's view too, it seems.
Robben is told to get up by the Norwegian referee after going down in the area, supposedly under a challenge from Cazorla.
Ozil has apparently been withdrawn due to a tight hamstring. Not much else to report in opening stages of second half.
Get well soon to Peter Bishop who has emailed in from his hospital bed in Munich. He asks: "I don't seem to remember Ozil being mentioned much. What's happened to him?" Well, he has certainly been a peripheral figure here.
Atletico Madrid are leading AC Milan 2-1 on the night and 3-1 on aggregate in the other last-16 tie taking place tonight.
Kevin Brown "can see Arsenal grabbing a creditable 1-0 win that will in no way help them progress", while Darren Parke is urging the Gunners to "make history" in the second half. On Twitter, @jackgun90 suggests: "Put Rosicky on, take Santi Cazorla off and push Chamberlain forward." Will that work?
Right, let's get to the emails first. Jake Shephard says: "It's been an interesting watch so far, Arsenal have been solid enough. However we're not playing for a 0-0 we need a 0-2 performance, which will mean giving the ball to Chamberlain more and probably putting someone like Gnabry on, because Ozil has gone missing again. We need people who want to play for the shirt and impress!! "
What did you make of the first half? What are Arsenal going to have to do to engineer chances here? Will their defence hold firm for another 45 minutes against the Munich machine? Let me know. Drop me an email at firstname.lastname@example.org or tweet me at @jonboy79.
Mertesacker helps clear but Oxlade-Chamberlain loses possession and then Koscielny has to get the ball away again.
Fabianski has to save as Vermaelen heads Alaba's left-wing cross straight down to the feet of Gotze, who strikes a low snapshot.
Almost at the interval now. Bayern have been the better team but Arsenal have defended pretty well so far. But can they find a way to use Oxlade-Chamberlain's spark and get on the scoresheet?
Arsenal need to threaten more - it's still just Giroud's header from a corner that's forced a save from Neuer.
Free header for Mandzukic as he tries to steer in Gotze's cross from the right but he can't get the ball on target.
Koscielny clears Robben's shot from inside the area. Bayern really carved Arsenal open there, and the defending was a little hesitant.
Alaba chooses to shoot himself on his right foot instead of playing in Gotze and the low effort goes well wide.
Arteta puts the ball behind after Robben gets to the byline on the right-hand side. Mertesacker heads the corner away.
Arteta has to time his challenge to perfection as Arsenal quickly find themselves defending in their own area.
Cazorla's free-kick hits the wall and goes behind for a corner. Giroud jumps high to meet the set-piece with a solid header but Neuer makes the save.
Superb skill on the dribble from Oxlade-Chamberlain, who is eventually fouled by Schweinsteiger. Surprisingly, no booking.
YELLOW CARD! Another booking for Arsenal, this time for Arteta. He's cautioned by the Norwegian referee for bringing down Thiago.
GOAL DISALLOWED! The free-kick from Thiago is met on the volley from Martinez but the assistant referee correctly calls offside.
YELLOW CARD! It's Podolski who is booked. Replays show Vermaelen went in late on Lahm, but it was Podolski who was cautioned - for kicking the ball away.
Arsenal yet to forge a meaningful opening, while Bayern have had three chances - but only one on target, from Schweinsteiger.
Wonderful pass from Thiago down the left channel for Alaba, but Bayern can't profit from it. Ozil switched off briefly and allowed the ball to be played inside him.
Best chance so far falls to Robben - Alaba plays Ribery into the left side of the area and he chips across the box for his fellow wideman, but he volleys the ball into the turf and it goes high and well off target.
Then at the other end, Podolski makes a run away from Martinez on the left and delivers a cross that's cleared by Dante. Martinez is briefly down on the ground after being caught in the face by a hand from Podolski.
I know we've got some Liverpool fans watching with us tonight, and they will be pleased to hear that some Bayern fans have unveiled a banner which reads: 'Justice for the 96, Never Forgotten' at the Allianz Arena tonight.
Now Bayern attack down the right through Robben and Lahm, but the offside flag is raised against the home team.
Almost a bad mix-up between Sagna and Mertesacker in the area, as Alaba tries to get free on the left side. The Gunners survive though.
YELLOW CARD! Great spot from Cazorla to release Oxlade-Chamberlain down the right and Dante blatantly blocks him off. The Brazil centre-back will now be suspended for Bayern's next Champions League match.
Schweinsteiger is adjudged to have pushed Mertesacker following a Bayern corner, and Arsenal get a free-kick.
The short free-kick goes to Thiago who crosses in and Mertesacker gets under the ball for a header. Sagna clears.
Arsenal are in yellow, Bayern in traditional red. Fabianski's had an early touch of the ball already
More on Miyaichi - He was not named on the Arsenal squad 'A' list, and was ineligible for the 'B' list as he hasn't been at the club for three yrs continuously (was loaned out to Wigan and Bolton).
Final feedback before kick-off - Adam Gillis on email: "Bayern are without doubt the best team in Europe and after demolishing Wolfsburg 6-1 at the weekend, I seen them being victorious again tonight with a comprehensive 4-0 win with goals from Robben, Ribery, Alaba and Mandzukic."
Here's Wenger again: "We've seen we can create dangerous situations. We need to score goals and I think both teams have chosen a very offensive formula. Let's hope it's a cracking game. We are focused and motivated. We want to show how strong we are and do something special."
And Pep Guardiola's view: "Winning 2-0 in London was a very good result for us, but it is also dangerous. We have a very good chance to go through, but we have to be in the situation that we really focus on the game. We have to bring our ideas across in the way we play, and know what the strengths are."
Speaking of history, here's what Arsene Wenger said before the game at his pre-match press conference: "It is a possible task, that is the most important thing. My team has quality and ambition. History is important in our belief. We know we can do it, because we have already done it (before). The way to win is to produce a top-level performance and turn up with quality and belief. The statistics are against us, but we have won 5-1 at Inter, we have won everywhere in Europe. We have had a few good nights in Europe but it would be absolutely great (if we won)."
Some historical hope for the visitors' defence? Arsenal have only kept three clean sheets in their last 27 away games in the Champions League, but the last two shut-outs have been in Germany (v Bayern Munich in March 2013 and Borussia Dortmund in November 2013).
It transpires Ryo Miyaichi was part of the Arsenal travelling group following some late withdrawals, but it's understood he is not eligible for their Champions League squad. You have to ask why he bothered going, although Munich is a lovely city to wander round...
Here's some of your tweets. @LethalTweet7 says: "I think Arsenal will go 1-0 up with a Giroud goal but then try and push for the 2nd goal but Bayern will score on the counter." @deanmurphy1983 is questioning Wenger's midfield: "Hopefully the mighty Gooners can produce something tonight, can't understand why no Flamini!" And finally @NavoSVP says: "Peculiar lineups... especially Poldi is a surprise (hope for FCB a shock) and a very crowded midfield- #GAME will be decided here."
Arsenal have come in to 15/2 with Sky Bet for the win on the night since the team news broke. As for Price Boosts, Schweinsteiger is out to 12/1 for the first goal, while Ozil is 18/1. A 4-0 Bayern win is available at 16/1, while the scoreline that would force extra-time - 2-0 to the Arsenal - is priced at 55/1.
As for that unused spot among the Arsenal substitutes, David Sinclair emails: "Where's Bentdner? He played against England last week - can't he warm the bench? Need a miracle tonight. Can't see anything but Bayern win."
The most optimistic email in so far isn't even from an Arsenal supporter! Here's Niall Ryan: "I'm a Liverpool fan so I know all about amazing comebacks... Bayern are an excellent side but I'm going for an amazing turnaround, 3-1 to Arsenal... Ozil to repay his £40m with a fantastic 90 minutes."
An Opta stat that shows the hosts' strength... Arsenal are the last team to keep a clean sheet against Bayern Munich in the Champions League, when the Gunners won 2-0 at the Allianz Arena on 13 March last year. Since then, the Bavarians have scored 32 goals in 12 games in the competition.
Referee for tonight's proceedings is Svein Oddvar Moen from Norway, who actually took charge of last season's last-16 first-leg tie between Arsenal and Bayern at the Emirates. His slightly controversial decision to award the hosts a corner on 54 minutes led to Lukas Podolski's goal that night.
Also getting in touch on email is Joshua David who says: "This should be a cracker tonight but I think Arsenal will win 2-1 with Bayern scoring first through Robben, but Mertesascker and Giroud giving Arsenal the win." Chris Green from Huddersfield fancies a 2-1 Bayern win, with Gotze and Mandzukic getting on the scoresheet for the hosts.
Jim Dunker has emailed in from San Diego to say: "Willing to hope for another Arsenal surprise, pulling for a 0-3 for the Gunners. Much like the USWNT, it wouldn't be a story without a shock humbling, like Wigan's latest heroics."
A bit more on Hayden, who'll already be more familiar to many Arsenal fans - he played 84 minutes in the Capital One Cup tie at West Brom back in September, and has been an unused sub on five other occasions this season.
Looking at the Arsenal bench, it appears Arsene Wenger has only named six substitutes. Mathieu Flamini is on the bench, along with 18-year-old Academy centre-back Isaac Hayden, whose versatility could yet be needed tonight.
Bayern won 6-1 away to Wolfsburg in the Bundesliga on Saturday and they lead the table by 20 points from Borussia Dortmund after 24 games played. After that emphatic win, Pep Guardiola makes five changes - in come Javi Martinez, Bastian Schweinsteiger, Thiago Alcantara, Mario Gotze and Mario Mandzukic. They replace Rafinha, Jerome Boateng, Thomas Muller and Toni Kroos - who all drop to the bench - while Xherdan Shaqiri will not be involved tonight.
So Arsene Wenger makes three changes to the Arsenal team that began the 4-1 FA Cup victory over Everton on Saturday. In come Laurent Koscielny, Lukas Podolski and Olivier Giroud in place of Kieran Gibbs (ankle), Yaya Sanogo (foot) and Mathieu Flamini. Wojciech Szczesny is of course suspended after his first-leg red card and Jack Wilshere, who also started that game, is injured.
And the Bayern team is: Neuer; Lahm, Martinez, Dante, Alaba; Schweinsteiger, Thiago; Robben, Gotze, Ribery; Mandzukic.
Here's Arsenal's starting line-up: Fabianski; Sagna, Mertesacker, Koscielny, Vermaelen; Arteta, Oxlade-Chamberlain; Cazorla, Ozil, Podolski; Giroud.
Confirmed team news should be with us imminently. Looking at the images coming in, I've stuck up one of Robert Pires and Jean-Pierre Papin - former Arsenal and Bayern stars respectively.
Bayern have won 11 of their last 12 Champions League games - they were beaten 3-2 on home soil by Manchester City on December 10, but Pep Guardiola's side still won Group D.
As always, I want to hear your views before kick-off and as the action unfolds. Drop me an email at email@example.com or tweet me at @jonboy79.
Arsenal are a whopping 20/1 to qualify with Sky Bet, having lost 2-0 at the Emirates in the first leg on Wednesday 19 February. As for the second leg itself, you can back the Gunners at 8/1 to win on the night, with the host strong favourites at 30/100. The draw is priced up at 5/1.
It's another tall order for the Gunners as, just like at this stage last season, they trail by two goals going into the away leg in Germany. A repeat of Arsenal's 2-0 victory 12 months ago would at least take matters to extra-time, instead of Bayern triumphing on away goals.
