Arsenal captain Thomas Vermaelen insists they're capable of winning the Champions League.

Vermaelen says Arsenal can win if the fans who booed them off after defeat to Blackburn Rovers get behind them at the Emirates tomorrow against Bayern Munich.

Vermaelen said: "The result against Blackburn was terrible.

"It's normal the fans are disappointed but we need them to believe as well. We need their support 100 per cent on Tuesday.

"Anything can happen in the Champions League.

"Is it realistic to win the Champions League? Why not? It's a tournament, I believe in our chances."
