Literally all these coaches apart from Tuchel ended up dropping him and most of them are low-block coaches who like his discipline and ability to nod away headers.
Dier obviously isn't a 'top quality' cb ffs. He is a very limited player having a good run in a team with out of form centre backs. He won't last long at Bayern as a starter. He's doing the basics right and that's been enough due to the form of Upamecano and Kim.
He was never exposed tonight like he was vs Saka in the QF first leg. Dier when he's not exposed is fine....
He was only dropped by all of those managers when his injuries affected his performance. All of them have SAID SO.
They all say he's a top quality CB. Mourinho wanted to pay 50 million for him ffs
