Bizarre role he's playing. He's a DM, but also a playmaker who attempts ridiculous number of high risk passes.
However, I do think he is quite good passer, and honestly 1 out of 10 those passes puts us through on goal, and it's one of the very few things that are working for us - if you don't count how many times it generates a turnover that is.
Seems to me like ETH has given up on playing football in any other, more complicated way than "just lump it forward". Those players can do better if used correctly. Casemiro can do better. He's asked to do too much, he should be just sitting deep and starting attacks. He can do it. He's just used in the wrong way now.
I also think he should not be allowed to make sliding tackles. He looks like a walking red card.
