He's 18 in august though Bman aka the start of next season, so he has to play more then. Still cameo appearances like, but he has to be included otherwise he'll go elsewhere. Barca were after him remember, it'd be hard to turn them down if he's frustrated by not getting game time.
Jose needs to start thinking where he can play next season, what position, inside forward, centre mid etc. That will show the cunt he's in the managers plans.
