Wenger said: “He was out for three months at a very important period of the season. For me he is very big player for us. Firstly because he is a winner and he is ready to die on the football pitch to win.
“Secondly because he is good reader of the game, good tactically and can bring a lot to this team
“He was very unsettled by his injury and he was desperate to play and come back. It was a big, big blow to him.”
