Arsenal boss Wenger has held discussions with Wilshere in the past few days and urged him to stay and fight for his place.
Mirror Sport understands the England midfielder’s red card in an Under-23s game against Manchester City on Monday night will not have any bearing on his future at the club.
Wilshere lost his temper following a bad challenge by City midfielder Matthew Smith, then squared up to Tyreke Wilson.
The 25-year-old wrote on social media: “Felt good to be back on the pitch at the Emirates even though it ended earlier than I thought. My passion and my hunger is back, buzzing for more games.”
It is a remarkable turnaround in fortunes for Wilshere, who feared his Gunners career was over after being told he could go.
Aston Villa, Newcastle and Swansea were among the clubs interested in the midfielder, who only has a year left on his current deal.
But Wilshere was left undecided as to whether to stay then leave on a free, fight for his place or try to push for a move this summer.
However, it now seems more likely he could be back in the first-team frame, having spent last year on loan at Bournemouth.
Wilshere broke his leg at the end of last season as his persistent injuries came back to haunt him again.
But Wenger has been impressed with his attitude and still believes in his potential, despite the years of setbacks.
Arsenal are not interested in buying another central midfielder and have put their faith in Granit Xhaka and Aaron Ramsey, with Mohamed Elneny and Santi Cazorla also in the squad.
And it now looks as if Wilshere – who has started two games for Arsenal’s Under-23 side – could now be pushing for a remarkable first-team return.
The red card he got with the U23s on Monday night will not carry over to the Premier League.
