He has it but needs the best training facilities and coaches. Lot of first team and still maybe wont reach PA. If i remember correctly he has injury prones and natural fitness 0 so it is random every time.
Kovavic is safe bet and if you need someone who can be a class from the start. And ofc you have the money to buy him.
As for his hidden attributes, I haven't looked at them but I can honestly say he has never had injuries problems on any of my saves and he always develops into one of the best.
Dont know who to sign for Man Utd first season. Will be used as a roaming playmaker/ Deep Lying playmaker.
If you could recommend anyone else i would be grateful. thanks in advance
