There is a top player in Maguire, but right now he's a liability.
Whoever comes in as manager needs to hand the captaincy over to Ronaldo and drop Maguire to the bench and make him earn/fight for his place in the team again. He just doesn't feel right as captain, he's not leading by example and is just missing that edge, I think it's even more evident by how he has reacted when the chips are down, we need someone stronger to captain the team. On recent performances he should definitely not be an automatic starter either and he needs to be dropped to avoid becoming complacent in future. If the new manager has half a clue the quality of coaching and tactics will hopefully benefit him massively.
He should be in our starting 11, but he needs a wake up call.
