There are two different sides in Maguire's case. One is people who were against the signing with point of saying he was never good enough defensively due to lack of pace & the other one is people who had no issue with the signing because he's better than what we had. The people who were against the signing is right now trying so hard to criticise him for every small mistake he's making even when he doesn't make the mistake they will still blame him.
I thought he's done very well so far, I don't know what game you were watching but I think he has brought in more composure in our defense, more forward passes from the back that can penetrate opposition midfield & statistically we had one of the lowest expected goal’s against. He's a massive upgrade of Lindelof which someone I never understand why we signed him in the first place, should have signed Maguire from Hull instead. To me once Tuanzebe is back he should be paired with Maguire not Lindelof and I think it will compliment Maguire's weakness, while Lindelof has everything of Maguire's weakness.
