Arsene Wenger looks on during the UEFA Europa League group H match between Arsenal FC and 1. FC Koeln.
Arsene Wenger has sent a warning to Jack Wilshere about what he needs to do by December to resurrect his Arsenal career.
Wilshere has played three times for the Gunners in all competitions this season since returning from a hairline fracture on his leg suffered while on loan at Bournemouth last term.
The midfielder is out of contract at the end of this campaign and speculation is mounting over whether his future lies away from the Emirates Stadium.

"Wilshere struggled historically with repeated injuries," Wenger was quoted by the Sun. "Nobody would question his talent. Nobody would question his exceptional ability to beat people with the ball. But in this job you need first health.
"That is what’s at stake for Jack Wilshere. Keep health and compete and be capable to compete.
"If he can play from now until December at the top level he will be back. If there are other setbacks then it will be difficult for him.
"It's a vital season, it's the end of his contract, a World Cup year. He's an Arsenal player since he's a kid so all that is at stake for him."

The point of the World Cup is a valid one for Wenger to raise, with Wilshere having not played for England since they were eliminated from Euro 2016 by Iceland in June last year.
The 25-year-old will be keen to be included in Gareth Southgate's squad, but is unlikely to be if limited to cup appearances and marginalised in North London.
West Ham fans are all too aware of how frustrating a perennially injured player is with Andy Carroll currently at the club, but his English counterpart could give them something distinctly lacking in their central midfield at the moment - creativity.
Wilshere has the rare ability to be able to unlock a defence with a pass and make driving runs forward and if he can stay fit, a move across to East London could be a great one for all involved.
