The 17-year-old has been linked with a loan move to Premier League rivals Burnley.
“It is possible, with one condition, that he plays,” he said. “Wilshere needs to play. Burnley is a good club which I respect. They play good football, but Jack must want to do it.
“I like the idea, but at the moment we are a bit short. Jack is in the squad nearly every game.”
