Would he come back though if that was the role? This season bar some games in Feb and March he's started pretty much every game. I think if he comes back on loan again it will be the same role as this season as first choice until he plays himself out of the team as he did in those months. If it's a warming the bench role he can just go back to Leeds and do that if they come back.
What can't be happening next season though is when that happens it's Young or that type of defensive player in final third. Desperately have to sign a young player with pace who can play there.
