The manager is very fond of the 18-year-old midfielder - no wonder little Jack commands his midfield.
At Bolton, Wilshere has being a regular face, he's yet to start a Barclays Premier League game for the Gunners but has started an incredible number of matches for the Wanderers.
Coyle said: "Jack wants to be an Arsenal player. All I am saying is if Arsene Wenger and Arsenal don't think he will play for them regularly at the start of the season, give me another six months. It will do him good. He would go back bigger and stronger. He is improving game by game.
"He is only 18 but he has got better. He's enjoying being with us and enjoying working with us," he enthused.
