His contract with the Gunners is set to expire at the end of the season and given that he is not getting regular game time, he could leave the club in January in order to try and push for a place in the England squad during next summer's World Cup.
The 25-year-old may not have played in the Premier League since April or scored a goal in any competition since June 2015, but there will always be managers willing to take a risk on a player of his talent.
Speaking ahead of Arsenal's trip to Watford on Saturday, Wenger said: "I believe that Jack at the moment is in the best form I have seen him for a long time".
"He is very close now to being considered like anybody else".
"He has played games since the start of the season and he will play many more".
" I don't see Jack being fully fit and not going to the World Cup."
"If he keeps going like he is he will go the World Cup".
Wilshere though has not played for his country since coming on as a half-time sub during last year's disastrous European Championship defeat to Iceland.
His early career has been devastated by injuries but every flicker of form commands attention because of a lack of genuine midfield options available to England boss Gareth Southgate.
Wenger added: 'We have plenty of good players but he is maybe more of a No 10 than any other player.
"I say on the left, but the boss told me before the game that he wanted me to come inside, get in the pockets [of space]".
