Long shot though as Flick took half of the B team on pre-season tour, and Prim wasn't one of them.
It will be Casado until Frenkie returns. But Prim will no doubt get shots in training and Flick will follow him closer than had Bernal been around.
Nico doesn't really add up. He is excelling right now for Porto in that AMC slot. Can he play DMC? Yes, but he even then better as the more progressive of the double pivot- that Pedri spot, and I'm not sure if that's what we really need right now.
But hey, if we got the 15-20m hanging around and won't affect future cap space, I would love to have him back. Solves the Frenkie issue if/when he is sold.
