If you stroll into a bookmakers today and have a wager on Arsenal to win at the Nou Camp, you'll get odds of around 15/2. Back Barcelona to beat Arsène Wenger's team on Tuesday night and it's a rather more stingy 4/11.

Those prices suggest that Arsenal have little chance of getting the victory they probably need to advance to the Semi-Finals of the Champions League. But their manager thinks this Quarter-Final tie is far more finely balanced than the bookies would have you believe.

Wenger saw his team outclassed for much of the first leg at Emirates Stadium but watched proudly as they fought back from 2-0 down to draw 2-2. Barcelona gave Arsenal big problems but the European champions wobbled on more than one occasion themselves. That gives Wenger hope that his team can defy those rather bleak odds at the Nou Camp.

"I think it is more balanced than the impression people have," he said.

"If you look at the game again, we analysed it very well. Many times they gave us big problems in the first part of the game but if you look at the number of chances we created through the whole game it is quite interesting.

"But I believe there is no room for patience now. You score goals tomorrow when you can but you need a big discipline, a big organisation for a big part in the game. It is for sure if it is still 0-0 in the last part of the game we can throw everything at them but we have to try to be very well disciplined and not to hide when we have the ball."

Like Arsenal, Barcelona are chasing a domestic title as well as Champions League success. But unlike Arsenal, Barcelona have a huge game at the weekend - 'El Clasico' against their old foes and title rivals, Real Madrid. However, Wenger is not expecting Pep Guardiola's team to show any signs of distraction on Tuesday night.

"They will not be complacent and I don't think they will be distracted," he said. "I believe that for Real Madrid they have four or five players to pick and I don’t think they have that game as a priority tomorrow night. They know they have a big game."
