I think hes excellent tbh. Very composed, has leadership qualities, good on the ball, takes charge of situations, dominant in the air and a threat at set pieces.
Since Rio, Vidic and Evra declined I've never really felt like we have anything set in our back 4 if we were to ever get to being a top team again. Players like Lindelof and Shaw had ok seasons at times and others had good runs of form, but I never felt they were more than average players who could play better than they were. Maguire and Wan Bissaka are 2 players who IMO can be big pieces for us in becoming a top team again and have probably been our 2 best players so far this season.
