Nope. I can't agree with that.
Maguire might not cheat in the same way as Fernandes i.e. throwing himself to the ground and screaming at the slightest contact, but as a protected united player he's proved himself to be just as much a cheat in his own way... In all my years watching football I've never seen a CB previously get away with so much blatant grappling and bear hugging of opposition players, literally wrestling players to the ground every week and never getting punished for it.
Plus he's as bad as Fernandes (and most other united players) when it comes to abusing and harassing the refs at every opportunity.
