Arsene Wenger believes Arsenal are ready to "go for it" and overcome Barcelona in next week's Champions League quarter-final return leg.
The Gunners looked down and out as Zlatan Ibrahimovic opened up a two-goal lead as the reigning champions put on a sumptuous display in the opening stages of the first leg at the Emirates Stadium.
However, his efforts were cancelled out by substitute Theo Walcott and a late penalty from Cesc Fabregas as Carles Puyol was dismissed for tangling with the Gunners skipper.
"He (Walcott) had a huge impact when he came on. He has qualities which can be useful on a big pitch like the Nou Camp. We can still qualify," claimed the Frenchman.
"We have to study how we can win the ball back. When we did that we always looked dangerous against them.
"We have to go for it. It would be a big achievement but we believe we can do it.
"It was a great football match with two teams who went for it. It was an exceptional match."
