Arsene Wenger has claimed that Jack Wilshere will only be out for "a few days" with the injury the midfielder suffered during the 1-0 victory over Sunderland.
The England international had to be replaced by Abou Diaby in the second half after complaining of a problem in his right leg.
Wenger told reporters: "Jack will be out for a few days. It's nothing bad.
"It was a very intense game. When the second goal doesn't come, you have to keep your nerve"
Arsenal are now fifth in the Premier League, four points behind rivals Tottenham Hotspur.
