Tuchel seems to like Rogers cos he plays where he is told to play, for England that is right sided,
Bellingham seems to think he can play where he wants, dropping deep, and then turning up on the left.
I think Morgan has benefited from playing for Unai, in that you play where he tells you or you don't play at all as Elliott is now finding out, Tuchel seems quite similar to Unai in that aspect.
