Arsenalâ€™s Alex Oxlade-Chamberlain is set to miss at least six weeks with a knee injury.
"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.
