The Gunners star returned to the north London club in the summer following a season-long loan at their Premier League rivals Arsenal.
Wilshere made 25 appearances during the 2016-17 season to prove his fitness before an unfortunate leg break in the second half of the season.
Arsene Wenger resorted to using Wilshere in the Europa League and the League Cup in the opening months of the 2017-18 Premier League campaign.
However, the 26-year-old’s performances have earned the England star a regular starting spot in Wenger’s first-team in the English top flight.
Wilshere started six of their Premier League games during the festive schedule to prove his ability to play two or three games a week.
Former Arsenal defender Keown believes Wilshere is in the form of his career at Arsenal.
“I thought Jack was coming back into the form we expected to see many years ago and I was really pleased to see him with the armband against Chelsea,” Keown told the Daily Mail.
“I’ve said before that Arsene Wenger should build the team around Jack.
“He was taken off with an ankle issue at Stamford Bridge and where he got caught, it’s happened to me and it’s painful. Wenger may not want to take any risks and leave him out against Bournemouth this weekend. It could be sensible.
“It is a worry that he is getting fouled so much. Jack asks questions, he sometimes gets caught and draws tackles. For me, if he makes it in the Arsenal team, then he makes it in the England team. This is as well as I have seen him play in a collection of games ever in an Arsenal shirt.
“He’s been in the engine room, making good tackles, winning the ball, his repertoire of passing, assisting, getting on the scoresheet – he can be the driving force. I just hope his latest injury is nothing serious.”
Wilshere captained the Gunners team for the first leg of their League Cup semi-final at Stamford Bridge on Wednesday night.
The Arsenal midfielder suffered a sprained ankle in the second half of the goalless stalemate in west London.
The Gunners are in sixth place in the Premier League table ahead of their trip to Bournemouth in the Premier League on Sunday.
