Arsenal's Alex Oxlade-Chamberlain is set to miss at least six weeks with a knee injury.

The 20-year old winger sustained posterior cruciate ligament damage in Saturday's 3-1 loss to Aston Villa with Gunners boss Arsene Wenger suggesting he will be out for just under two months.

"He will be out for at least six weeks. He has a posterior cruciate problem, a ligament which is stretched," Wenger said.

"We don't think it will need surgery. He is consulting tonight, but it will be at least six weeks out." However, Oxlade-Chamberlain himself posted on Twitter that perhaps the injury may keep him out until November.

Gutted i'm injured so early in the season. But I'm going to be working hard to hopefully be back playing in 3 months.Thanks 4 all ur support — Alex Ox-Chamberlain (@Alex_OxChambo) August 20, 2013
