Nicklas Bendtner believes Arsenal can upset Barcelona at Camp Nou and secure a place in the UEFA Champions League semi finals.
The Gunners have it all to do in Catalunya on Tuesday evening following a 2-2 first-leg draw at Emirates Stadium.
However, it might have been mission impossible had Arsene Wenger's side not battled back from two goals down after Zlatan Ibrahimovic's brace
Arsenal showed their mental strength on Saturday by securing a last-gasp home win over Wolves thanks to Bendtner's close-ranger header.
Although the Gunners will be up against it in Barcelona, the Danish striker is quietly optimistic of upsetting the odds.
"We showed belief and we showed character. I still think we can go through," said Bendtner.
"It will take a monumental effort to win in the Nou Camp.
"But Barcelona have lost there this season in a group game against the lowly Russians of Rubin Kazan and they will also be without first-choice central defenders Gerard Pique and Carles Puyol."
Meanwhile, manager Arsene Wenger believes Pep Guardiola's side will be worried by the form of pacey winger Theo Walcott.
The England international impressed off the bench in the first leg and was one of Arsenal's better players against Wolves and the French boss has hinted he will start in Spain.
"They will be worried by Theo," stated Wenger. "I'm very happy that he had such an impact on the game.
"You have big players on the bench and when they come on you don't forget that they have qualities to make an impact.
"Theo stretched out the space. In the second half we had twice as many passes than in the first, as we kept the ball better - so we were better able to alert our wide players.
"Theo has a chance to start the game in Barcelona."
