We got matey Bastian and blind instead just as Moyes brought matey fellaini and Mou brought matey Matic. That what happens when you give full control to the manager.
How many matey players did Pep buy? With whatever structure you have, with or without DOF, if you manager whom you just hired and obviously trusted, want 1 key player as last piece of his puzzle, would you not support him? If that player cost 200m you can decline base on commercial reason, but not a 40m player. If your manager want yet another DMF beside your current 3 DMF (like Conte did) then your DOF should do his job. If your manager want yet another left winger like Sanchez while you already have 2 key players playing on the left, your DOF should say something.
Out of all the deadwood that we recruited, I would say a good DOF can only filter half of them.
YES - Fellaini, Schneiderlin (if he has done enough research), Sanchez, Rojo (too short), Dalot, Darmian (too slow)
NO - Blind (versatile enough, can you say no?), Bastian, Matic, Bailly, Lukaku, Depay,
