It looks a tall order given the sparkling displays Barca have treated Europe to and with 90,000 fans baying for more, Arsenal look to have the odds firmly stacked in a pile against them.
And yet…The fighting spirit displayed in coming back from 2-0 down last week was stirring stuff and ardent Gooners will remember that Arsenal have reserved some of their finest European performances for away trips (5-1 at Inter Milan? 2-0 at AC Milan anyone?).
The team may be rocked by the major injuries that have blighted the squad but stranger things have happened and 15/2 is a huge price for them to get the win they need tonight. Worth a flutter?

The win looks the most likely route to securing qualification as Barca's away goals will be hard to better in the draw - however, 2-2 would send the tie into extra-time and even penalties.
If you fancy The Gunners to just go through and you aren't sure or don't care how, then it's 9/2 for a semi-final berth.

Wenger is unlikely to be too gung-ho in his approach early on, with his eyes set on containing the free-flowing football of Barca on their home turf and perhaps using the pace of Theo Walcott to hit the Catalans on the break. A solid defensive showing is surely key so either Mikael Silvestre or Sol Campbell will have to be the rock and it could be that the odd goal will be the aim for the Gunners, although there is huge money to be made if you fancy Arsenal to upset the odds - 75/1 for 2-0?
Maybe that is fanciful thinking - if Barca get the early goal you do fear for the young and relatively inexperienced Arsenal team. Barca are 10/11 to be winning at both Half Time and Full Time and 8/1 to win the match 3-0.
The 2-2 draw that would take Arsenal into Extra Time is a 13/1 shot and a win on Penalties for either side is currently 80/1

Messi is of course man of the moment - the best player on the planet and seemingly unstoppable. No surprises then that he is just 13/5 to score the first goal, 11/5 to score 2 or more goals and 6/1 to even bag a hattrick. Ex-Arsenal terrace darling Thierry Henry is not on the best of form at the moment but fuelled by the amazing reception he got at the Emirates, could he be the man to come on and break the deadlock as well as Arsenal’s hearts? - he's 9/2 to score first.
Nicklas Bendtner was the hero for Arsenal's Premier League bid on Saturday and he could be the man to spearhead one of the great European results - his touch and physical presence could be the key to unsettling Barca's defence and he is 9/1 to break the deadlock.
Theo Walcott is one player Barca fear and if his turn of pace can get him clear at any point, he has a good chance to repeat his match-turning performance of the 1st Leg by sticking one away - he is 11/1 to score first.
Elsewhere, midfield maestro Samir Nasri must shoulder the creative burden in the absence of Cesc Fabregas - a repeat of his wonder goal against Porto would be handy - and he is a tasty 16/1 to score first
