Has Casemiro improved under Ten Hag?

He was WC at Madrid, but also had WC players around him. Here hes head and shoulders our best midfielder. so stands out even more. Dont think hes playing any better than he was at Madrid.
 
He is an amazing Player but recently he has looked very jaded, wonder if that is because he has been overplayed and heaviliy relied upon? It is more intense in the English Game of course, every game higher tempo etc etc.

I think he has been on "Par" to use a golfing term, he has done exactly what a £70M superstar signing should have done....I do wonder though, can he keep this up for say another 18-24 months? I would hope so and that the lads around him can learn off him
