Being light in midfield isn't really much of a problem when you play park the bus hoofball... 8 defenders and 2 quick lads upfront are all you need.I’m surprised they are letting him go as he was one of their better players last year. Are they going to go into this season thinking Casemiro can improve on how bad he was last year and Mainoo still learning his trade will have a dip in form. They are very light in the middle of the pitch which is certainly their biggest weakness in being able to dominate the middle of the park so they can impose themselves on teams.
