Wilshere, 25, has been plagued by injuries throughout his career, which has curtailed his progress at Arsenal.
He has recently come back into contention at Arsenal after suffering a broken leg during his loan spell at Bournemouth last season.
The midfielder has impressed in the three appearances he has made in cup competitions so far for Arsenal this term, but he is yet to feature in the Premier League.
And with his current contract set to expire next summer, Wenger has hinted that he needs to get a run of games under his belt from now until December or his future at the club could be in serious doubt.
“Jack Wilshere struggled historically with repeated injuries and no one could question his talent, nobody would question his exceptional ability to beat people with the ball,” Arsene Wenger told beIN Sports.
“But in this job you need to have health. The requests and demands of the competition, physically, are so high and you can only be at your best if you can play at least 10 games on the trot. That’s what’s at stake for Jack Wilshere.
“He needs to keep his health and be capable of competing. If he can play from now until December at the top level, he will be back. If he has other set-backs then it will be more difficult.
“It’s a vital season because he’s nearing the end of his contract, it’s a World Cup year and he has been an Arsenal player since he was a kid, so all that’s at stake for him and for us as well because you’d love a player like him of that quality to come back.
“In fact he had a very good game in BATE Borisov, especially a brilliant first half where he was back to his best, so he’s not far away now. Let’s hope in the next two or three weeks he can play regularly in the first team.”
If he stays fit, he could reportedly be handed a new four-year deal.
