Wilshere will be back in the Arsenal team if the 24-year-old proves he can go a full season without injury at Bournemouth, says the Swede.
"Everyone knows Jack is an amazing talent," Ljungberg told the Daily Mail. "He's an amazing player. I love him.
"But I think if he can play 38 games for Bournemouth then he will be back here playing and starting again. I just think he's had bad luck.
"He plays well, then after six or seven games, you think, 'Oh he's back'. Then he gets injured again. That's a vicious cycle.
"I think if he can do that for 38 games, next season he will be back and he will be starting again."
