Thank you for joining me this evening. This match was billed as a blockbuster and it did not disappoint. It is all to play for at the Nou Camp in the second leg.
It is the last kick, and what an ending to a great game which came truly alive when Ibrahimovic initially equalised with 11 minutes remaining. PSG deserve to go into the second leg with hope, they worked their socks off.
In what may be the last kick of the game, Matuidi makes it 2-2 after firing home from Ibrahimovic's knock down. Valdes should have saved it but was caught going the wrong way and ended up helping the ball in. Fantastic late drama at Parc des Princes.
PSG are almost clean through on goal as Ibrahimovic heads down Thiago Silva's long ball for Gameiro but the bounce is awkward and Alves is first to get to it.
That goal has really lifted the hosts and just imagine the noise inside the stadium if they went on to get another!
Controversial equaliser for PSG as Ibrahimovic converts having been in an offside position when Thiago Silva's thumping header from a free kick came back off the post.
Alba and Mascherano collide with each other and both are hurt but it allows Ibrahimovic to be onside to finish a chance. His effort is poor and straight at Valdes but Barcelona are furious play was allowed to continue.
PSG break from the corner and have free kick on the left edge of the box following Mascherano's foul on Menez. Yellow card for the Argentinian.
Villa goes down eagerly from the challenge by Alex, earning Barcelona a free kick in a central shooting position.
Maxwell does really well to create a chance for PSG, but the pass would have been the better option rather than a shot from a tight angle which Valdes saves. Menez and Ibrahimovic were both in space.
Poor foul from Beckham now as he is booked for sliding in recklessly on Sanchez. Xavi and Alves standing over the free kick.
Fabregas delivers a good cross for Sanchez but the Barcelona forward doesn't connect properly and it is an easy save for Sirigu.
Matuidi intercepts to stop Barcelona in their tracks and lead a PSG break but they can't get an attempt on goal.

A succession of Barcelona corners now. Ibrahimovic gets his head on the second one to clear but possession is back with the visitors.
Sumtuous flick from Ibrahimovic towards Matuidi inside the Barcelona box but Pique does well to prevent a shot on goal and wins a goal kick off the Frenchman as a bonus.
Jallet cross for Ibrahimovic at the far post, but the Swede's touch lets him down and a good opportunity goes begging for PSG.

Harvey S writes: 'Barca were always going to score, -('s what they do....but they defend like Rocky Balboa. We've seen that all season long - actually we saw it over the weekend! I reckon it'll finish 1-1 - or PSG might pinch it last minute!'
Thiago Silva is one step ahead as he interferes with a Barcelona attack. PSG subsequently come forward but Lucas gives it away trying to beat his second man.
Ibrahimovic delays his shot and ends up running into traffic before losing possession in the Barcelona box.
Huge cheers from the crowd for a penalty as Masherano and Matuidi collide at the other end. Nothing given.
Matuidi's dodgy clearance from the corner allows Busquets a free shot from the edge of the area. He hits it well but Sirigu is well placed to save.

Liam Eyre writes: 'barca will win 3-1 lesson will score again n iniesta. Lavezzi will score for PSG barca looking very strong!!!!!!'
It is quite likely Messi will have to be replaced at the break - could that potentially change things or has he already done the damage?
Can PSG get back into this game, or will Barca run away with it now they have the lead? Let me know by emailing email@example.com or tweeting @obell1990.
Paris St Germain are now 10/1 to battle back and establish a first-leg lead and 4/1 to salvage a draw, while Barcelona are price boosted to 9/1 to run away with it and win 3-0. Also available in Sky Bet's half-time price boosts is David Beckham to score next at 20/1, while Lionel Messi is the 4/1 favourite to net next.
An entertaining first half ends with Barcelona in the lead. Could have been a different story, however, with Lavezzi hitting the post early on and PSG creating some good chances for themselves. Barcelona have had much more of the ball though, so the hosts will need to take their opportunities much better if they are to take anything with them to the Nou Camp.
Could be an injury for Messi who is rubbing the back of his right leg. Meanwhile Beckham's inviting cross into the box is headed well clear by Pique.
Messi almost adds a second as he runs at the PSG backline before trying to curl a shot into the top left corner. Just off target.
PSG will rue missed chances in this first half but need to make sure they don't lose their focus now as there is still a long way to go in this tie.
Barcelona now controlling possession in the hosts' half following the goal, looking a lot more comfortable now they have the lead.
Messi finishes from close range but it was made easy for him by the superb cross from Alves with the outside of his boot. Brilliant assist.
Creative work by Sanchez as he dribbles forward before feeding Villa, who tries to flick it back into the path of Sanchez but doesn't get enough contact and PSG clear.
Alba's cross from the left takes a deflection and almost finds its way to Iniesta in the six-yard box, but Thiago Silva makes sure he gets there first.
Alves has to work hard to challenge with Ibrahimovic in the air, but he does really well and sees the ball safe.
Great chance! PSG attack with such speed after Alex wins the ball with a sliding challenge. Lucas bursts forward before playing it to Ibrahimovic, but the Swede's shot is not hit smoothly and goes wide.
Great stuff by Thiago Silva as he watches the ball and times his challenge on Messi perfectly, with the Argentinian threatening inside the PSG box.
Brilliant work from Lavezzi to win the ball back for PSG inside the visitor's half, but his team mates can't keep hold of it. They are doing an excellent job of pressing Barca in their own half though.
The Swede takes is himself and it is a thunderous effort on target which Valdez does very well to beat away. PSG looking more than a match for their opponents so far this evening.
Pique is booked for a mistimed slide in on Ibrahimovic, leaving the home side with an excellent shooting opportunity just outside the area.
The ball finds its way to Iniesta on the edge of the box, and he is given enough time to curl a delicate shot goalwards, but it goes just wide.
Pastore's powerful shot has Valdes troubled as he parries forward, but the Barca stopper clutches on to the ball at the second attempt.
Villa very almost gets on the end of Iniesta's through ball but Sirigu is quick off his line for the hosts.
PSG hit the post! Lovely bit of play from the hosts results in Pastore squeezing his way through on goal only to be denied by Valdes's right post.
PSG have a free kick just inside Barca's half now and will try string a few passes together themselves now.
Alves is penalised for a little push on Maxwell as he advances on goal. Barcelona with plenty of possession in the opening minutes, as you may have envisaged.
The visitors wearing their orangey/yellow away top with PSG in their home colours. Atmosphere is electric at Parc des Princes.

Thanks for all the comments so far, it just shows how eye-catching this fixture is! Keep them coming throughout the evening.
Harry writes: 'Thinking about them lineups with Beckham and Imbrohimavic in there Nd then for Barca Messi and Villa, I think that this could well be a game for PSG to get the advantage, I predict 2-1 to PSG'
Cheshire Kat writes: 'Can see Beckham getting the opening goal for PSG but Barca taking charge of the game with a 3-1, 4-1 win!'
Gordon Phillips writes: 'Three years ago Fabregas was captain of a great club, one of the best midfield players in the world, already at 23 having a world cup and european championship winners medal, having made the pass that won the World Cup. Now he sits on the bench for big matches. Come home Cesc. Barca still to win overall and draw 2-2 tonight.'
Many eyes will be on David Beckham tonight. Can he handle the likes of Xavi, Iniesta and Messi? It's a tall order for the veteran, but one thing we should know is that you can never write off Becks. This really should be an exciting game.
Rafee Ahmed writes: 'What a sensational and mouth watering match this is with both teams in form just hoping for some quality goals from both sides..PSG with some serious talents have a chance tonight the likes of Moura, Lavezzi and of course Ibrahimovic...3-1 to PSG'

I think PSG are too big at 7/2 and would advise those looking for a bit of value in tonight's game to go for Lucas Moura to score in a home win. That is available at 17/2. Alternatively, Lionel Messi's price to score first has been boosted to 12/5 which is always a sound bet. How about David Beckham having an evening to remember? You can get with an enhanced scorecast at 85/1 for him to score first and the game to be drawn 1-1. Go to www.skybet.com to place your bets.
Barcelona are odds-on to establish a first-leg lead tonight. The Spaniards had to do it the hard way in the previous round as they lost their first leg 2-0 at AC Milan, prompting their outright price to drift out to 5/1, but were reinstalled as favourites again after prevailing 4-2 on aggregate. PSG, in contrast, drifted out from 18/1 to 33/1 after being paired with Barca, but have been handed a boost with Zlatan Ibrahimovic's two-match ban being reduced, enabling him to face his former club. The Swedish striker is the 5/1 second favourite to open the scoring behind Lionel Messi, who has scored six goals in his last four games and 54 in all this season. Barca can recall Andres Iniesta, Xavi and David Villa after the trio were rested for the 2-2 draw with Celta Vigo at the weekend, but captain Carles Puyol remains sidelined. Carlo Ancelotti had so such luxury of rotating as his side edged Montpellier 1-0 on Friday evening, with substitute Kevin Gameiro netting the winner.

PSG: Sirigu; Jallet, Alex, Thiago Silva, Maxwell; Lucas Moura, Beckham, Matuidi, Pastore; Lavezzi, Ibrahimovic.
No better way to start than with the team news, and there is one name that stands out - David Beckham. He starts for PSG tonight! Here is how both teams start...
