The problem isn't his commitment, his availability or his professionalism. It's that his basic characteristics as a defender are not compatible with how we want to play, so he is only used as a last resort. He is way too slow, and not nearly as good on the ball as he is sometimes given credit for. On top of that he is quite error prone. The evidence for this is ETH using Luke Shaw in central defense before him. Playing a high line with Maguire is just not a good idea. Varane is the opposite as a defender, but obviously struggles with availability, which is a problem.
That's why some people wanted rid of him so badly. We have a very high paid player, who used to be captain, who will not be used much before of the type of player he is. Maguire is not as bad as some like to suggest, but his strengths would just be utilized much better in a different side.
I appreciate that football is a game of opinions but with the sheer amount of focus on Maguire in the media + the constant microanalysis of his game since we made him the world's most expensive CB, I feel we've completely lost sight of the fact that he's still a top centre half.
It feels to me like ETH came in determined to move on from Maguire, but can we honestly say we've improved defensively? I'm not convinced, personally.
We talk about the high-line not suiting him, but it doesn't suit ANY CB if they're consistently exposed by an absent midfield and a weak press - something we've seen this season with Martinez, Varane and Lindelof.
Let's be honest, if Maguire had featured in the 0-7 vs Liverpool or the 3-6 vs City he'd have been savaged. If Maguire had performed as Martinez, Varane and Lindelof have this season, he'd have been savaged.
I'm not hear to argue with people about Maguire. Most people have made their minds up, he's a meme, he's the world worst centre half, he's a donkey, he's a laughing stock...but I sometimes think be careful what we wish for, because we've bombed him out the side and blamed him for all of our problems...and yet we might still be a better team with him in it...
EDIT | Few quick stats from last season...
Premier League 90-mins/Starts = 8
Premier League wins = 6
Premier League clean sheets = 4
Can't have been that much of a problem can he? The two games we didn't win with him in the team were the infamous Brentford
and Brighton games at the start of the season. Did ETH discard him too quickly following those defeats?
