That’s according to player turned pundit Tony Cascarino who reckons the England international is at a crossroads in his career.
Wilshere spent last season on loan at the Cherries but failed to impress and broke his leg towards the end of the campaign.
Cascarino says injuries have taken their toll and Wilshere is now lagging behind the likes N’Golo Kante and Nemanja Matic in the Premier League hierarchy.
Cascarino told The Times: “He seemed to join Bournemouth because his friend Benik Afobe was there, rather than pick a club where he was going to prove himself.
“Eddie Howe saw that he needed to play three in midfield to accommodate Wilshere and, midway through the season, the England man was on the bench.
“Howe wasn’t in a hurry to re-sign him as he did with Nathan Aké, who was on loan from Chelsea and then joined permanently for £20m.
“Wilshere should have moved abroad —despite the language barrier, the slight isolation forces you to focus on football.
“Arsenal ace Jack Wilshere struggled at Bournemouth ”
He has much to prove now. The modern-day midfielder needs to be so athletic —can he compete with players such as Kanté and Matic? Can he create and score goals? Can he play 90 minutes regularly? Is he in control of his emotions? Is he free of injuries?
“I hate to write people off because I’ve been there myself.
“If he is over the injuries and has the right attitude he can still be a top Premier League player. But it’s now or never.”
Arsenal face Liverpool at Anfield on Sunday but Wilshere is not expected to feature.
