So there isn’t a gulf between Robson and Carrick ?
Now you mention it, the gap between Carrick and Robson is probably bigger than the gap between Carrick and Case. I just mentioned Robson in passing to rebut the “look what he’s won” argument.
I don’t think many are saying Casemiro isn’t great. He looked good to me even when he was rusty. Carrick was good, as well, and was a bit better at passing and creating than Case is.
I would generally choose Case over Carrick, but that’s not the argument. They play a similar position but in a different style. Both do / did a good job.
It also depends who else you’re going to put in there. A pair of Case plus Eriksen is nicely balanced but if I have to pick either Case or Carrick to play in a midfield two with McT or Fred then it’s not such an easy choice - Carrick would provide better balance in that case.
Carrick probably is more appreciated by Utd fans than by anyone else but his ability is not normally denied. In the last 50 years he is one of the best we’ve had in that deep midfield position. He probably would have been more appreciated on the continent.
