who would you have then? Casemiro can't play as the single defensive midfielder, he's not quick enough to get back and track runners. Wolves midfield ran us ragged, Maddison had a field day against us. Casemiro's lack of pace is compounded when he plays with Eriksen , McT is not defensively strong enough to compliment him, and Mount can't play in that deeper role, same with Bruno as conceding possession back there is dangerous. Not ideal with Bruno on the right, but he has played there before, he played there and scored in the 2-1 win over City last season. That day we had Casemiro, Eriksen and Fred, with Bruno and Rash on the wings. Casemiro has been pushing high up the pitch this season, his problem is, when the move breaks down. he is not quick enough to get back ,and he doesn't have adequate help in midfield to help. Amrabat will help in that regard. Mount could also play right when he is back. That wouldn't upset the balance, in fact if anything it would help, as both would be looking to get passes into the box, as opposed to Anthony running down wing, stopping, turning and then passing it back.
