Arsenal manager Arsène Wenger is convinced their triumph over Barcelona back in 2011 can be a huge factor as they head into the Champions League last-16 match.
The Gunners thrashed the La Liga giants 2-1 at the Emirates Stadium five years ago thanks to goals by Andrey Arshavin and Robin van Persie. And speaking ahead of the match between the Gunners and the Champions League champions, Wenger is upbeat as he reckons they can upset the Catalan club again.
“The memory [I have] is that the winning goal was scored by Arshavin after we suffered for a big part of the game - we should be encouraged by that,” the Frenchman told Arsenal Player.
"We suffered in the first half and in the second half we slowly came back into the game and became very dangerous.
"That should help us in our [upcoming] game against Barcelona. If we have uncomfortable moments then we should have in our minds that we can still win even if it is difficult.
“It was really special [to win in 2011]. What I also remember as well is that it reminded me of how football is really as a team because you can deliver something exceptional.
"Three or four days later we went to Leyton Orient and drew in the FA Cup. In the same week that we were on a high, we were down again, but it will certainly be remembered as one of the exceptional nights at the Emirates.”
