If other clubs rate him as much as he rates himself then a move to Barca, Real, PSG etc will be on the cards. Can't knock ambition, its a big factor, but I think at 21 his place within CL side will be amongst the squad - not always a first name on the sheet. He needs to play, if he becomes the player he already thinks he is then champs league will come.
He could go to Celtic, they are in champs league...
