Needs to find a new identity in Flick's system. Looks like he is playing at a different wave length to the rest. The 10 position also fits him very poorly to be fair.
He cant play AM other than a runner as technically he is not great having eye for pass to open up game often or pull it off and the other side of it is he is to slow to have much impact driving with the ball... also he doesnt score many goals in career to date.
It is still the position most likely to play though as him at DM/double pivot would be an utter debacle both on and off the ball.
His most suited position is Pedris but he is miles and mile off Pedri on the ball and miles off FDJ also who would play there if Pedri out and Casado goes DM.
AM is where he is most likely to play as can have a role that allows for pressing and less quality is the reality at the moment.
