I agree with both JSP and Rich.
Maguire is an average defender in this league, he's somewhere in the middle. At least, when he came to us, I'd say he's in the middle, but this season he's well below average. He was never going to be a world-beater. He has huge boots to fill, with players like McGrath, Pallister, Bruce, Stam, Rio, Vidic, et al., becoming legends at this club. He's not even at the level of Smalling, though, and that's a huge problem.
Maybe he played through an undisclosed injury, or maybe the Greek punch up fecked up his mind. Either way, he was a disaster this season. I don't trust his decision-making when he has the ball, I don't like how he reads the game and I feel he's constantly over-committing and stepping up too high and too early, he doesn't know how to show his man to the outside, gets turned like a child, is slower than an oil tanker, and his secret weapon coming into the team was his massive head that was supposed to translate into goals from corners, and he hasn't delivered. 6'4" and you don't see him dominating, it's astonishing.
If ETH brings in a CB this summer, I'd expect Maguire to [become] 3rd choice behind the new CB and Varane. I'd personally move him to 4th choice behind Lindelof as well because I just don't see Maguire correcting the errors in his game to function in an ETH team. Can anyone really say they think Maguire would work in Ajax? That's the template and that's the style, and there's no room for a limited player like Maguire. Plus, he's 29, he should have been at his peak the past couple of seasons, so it's probably all down from here.
If a decent offer came in, I'd sell him.
