Arsenal boss Wenger: I wanted to sign AC Milan ace Ibrahimovic
Talking ahead of returning to the ground that his team beat Milan on in 2008 at this same stage of the competition, Wenger identified the key threat in the opposition - Ibra.
"He is a great player," Wenger told Arsenal's official website. "If you look at his record, at what he has won, he has his own personality based on a strong belief in himself.
"That is a quality at the top level that can sometimes be seen as over-confidence but I don't think he is because he turns up with performances in the big games.
