The same newspaper report also states that midfielder Tomas Rosicky suffered a muscular injury to his thigh during Saturday’s win over Burnley and could be out for as long as eight weeks after making his first appearance of the season at the weekend.
Wenger also provided an update on striker Danny Welbeck’s progress has he bids to improve his fitness following his lengthy lay-off with a knee injury.
Wenger said: “[Welbeck] is not completely ready but he is not far. He needs a game or two because he’s been out since last April. The Stoke [under-21] game is too soon because he only had one session with the team, and that is too short.”
Welbeck has not featured for the Gunners this season after undergoing surgery back in September.
