The thought is that it's only a matter of time before he signs, but his agent is smart dragging it out now he has appeared in the first team squad so he gets better terms. I bet we were offering him something like €0.3m as an 18 year old rookie, but he might be offered half a million by Leipzig. Kean got just over that but he was a striker.
When he signed he picked Juventus because it was somewhere he thought he could become a great defender.
