“Maybe he is less elegant and the visual impression is less pleasing but he is efficient and intelligent," Wenger told reporters.
“He combines well with both Vermaelen and Laurent Koscielny. They are good partnerships. He is a bit better at positional play.
“I have three good centre-backs. I can’t be wrong when I make a decision because all three deserve to play.”
Arsenal, who travel to Fulham on Saturday, currently sit fourth in the Premier League, two points ahead of Tottenham. A win for Wenger's men at Craven Cottage would see them leapfrog Chelsea in third.
