Stewart Robson has urged Jack Wilshere to quit Arsenal as he does not believe Arsene Wenger can help him reach his full potential.
Wilshere has seen another season go by blighted with a succession of injuries and was the subject of some heavy criticism from former Manchester United star Paul Scholes on Tuesday night.
Scholes was of the opinion that Wilshere has failed to improve since he first emerged as a 17-year-old and former Gunners star Robson believes the blame for that can be placed firmly on Wenger's shoulders.
“Jack Wilshere can be a world class player,” he told talkSPORT. “I’ve seen him from a young boy and he’s an outstanding footballer.
“Paul Scholes is right though, he hasn’t developed as well as everybody would have liked him to.
“He lacks discipline. He wants to get on the ball and charge into tackles, there seems to be no discipline.
“Who does that come from? The manager. Wenger has to make sure he has a role in the side where he knows what to do when does, and doesn’t, have the ball.
“He can be petulant at times. Why is he petulant? Because the manager is petulant on the sidelines and it’s never been sorted out.
“If Jack gets the right manager in charge of him, and the right sort of coaching, he will become a world class player. Arsene Wenger in my view is not that manager.”
Wilshere's latest injury has coincided with a serious dip in Arsenal's form, losing 6-0 to Chelsea before drawing 2-2 with Premier League strugglers Swansea at the Emirates Stadium.
That form has put a lot of pressure on Arsene Wenger's position as manager and, with his contract expiring in the summer, many believe his time in north London is up.
Robson says that Wilshere could succeed at Arsenal but that the manager must change if he is to fulfill his potential. If Wenger stays, Robson is adamant that Wilshere will have to leave.
“Like many players that have gone on to become top players, sometimes you have to move,” he said. “Jack Wilshere, at some point, may have to move away from Arsenal.
“If Arsenal change the manager and someone comes in who’s really disciplined and can get the best out of Wilshere, then Arsenal will still be the right club.
“At the moment though, with Wenger in charge, I’m not sure Arsenal is the right club for him.”
