And Wenger is confident Arsenal have learnt lessons from last season, which saw the Gunners lose the Carling Cup final to Birmingham City, and suffer premature exits in Europe and the FA Cup in the space of a fortnight.

“In every single competition we are, of course, in a position where we want to win our games.

“It makes me confident [this time] because I feel the team has the mental strength and a fantastic attitude on a daily basis. And from what we have learned from last year.”
