Maguire reads the game as well as anyone in our defence, plus he's more than comfortable on the ball, with a wide range of passes available to him. He hasn't shown us that this season due to his form falling off a cliff, but he isn't alone in that department - the entire first-team squad (bar Ronaldo) has been a country mile from their best form this season.
I'd be willing to give him a pass this season, personally, along with several other United players. I don't believe what we've seen from him over the past 12 months is a fair reflection of his capabilities, ditto many other squad members. I can't say the same for Lindelof, though, as he's always appeared cowardly to me. I don't think he's cut out for the PL.
