Santi Cazorla: Arsenal midfielder could be out until March

Santi Cazorla is yet to score for Arsenal this season

Arsenal midfielder Santi Cazorla could be out until March, manager Arsene Wenger has revealed.

The 30-year-old Spain international suffered a knee injury in the Gunners' 1-1 draw at Norwich last Sunday.

The club are already without midfield colleague Francis Coquelin for about three months following a knee ligament injury.

However, defender Laurent Koscielny and forward Theo Walcott could return to face Sunderland on Saturday.

Alexis Sanchez is out with a hamstring injury he suffered at Norwich, with Wenger defending his decision to play the Chile international against Norwich last weekend.

Sanchez had suffered a minor hamstring problem against Dinamo Zagreb in their previous game but had said he was fit to play.

Wenger told Arsenal's pre-match press conference on Friday: "Sanchez had four weeks' holiday [after the Copa America]. He was tested in some games, had all the sports science to play.

"No-one suggested he could injure a hamstring or back when he was pushed into a camera [pit]. That shocked everyone.

"I am not expert enough, but if you want to blame me, no problems."
