Once regarded as one of the brightest young hopes in English soccer, the 24-year-old fell out of favour at Arsenal after managing only 17 games in two seasons blighted by injury and joined Bournemouth on a season-long loan in August.
“Of course I love Arsenal, but if there comes a time when I have to leave, then I have to leave,” he told British media. “If I go back and I'm still not playing then, of course, I will have to think about things.
“At the moment I'm concentrating on Bournemouth. I want to put myself in a position where I go back next year and I'm a better player and I can play week in, week-out.”
Wilshere, who has been recalled to the England squad for Friday's World Cup qualifier against Scotland and a friendly against Spain, also said his move to the south coast club was a much needed boost.
“It was good for me. For my head. I wanted to get back playing week-in week-out, being involved in the Premier League. I have missed a lot of football,” he said.
“I missed the fight of the Premier League, being involved in all the big games and making a difference for a team and I wanted to feel that again, and almost fall back in love with the game again.
“When you are injured... it is hard. It is difficult. I needed it for myself.”
