He'll never play box. Just watched Chelsea against Stoke and can't see who they could have left out for him. Oscar started, Willian came on. They had Schurle starting along with Matic in the middle.
He might make the bench if he's lucky. Players really do just move for money don't they!
He will rotate with Hazard, they also move for top teams especially when they have enough confidence to compete with anyone.
