I think while slightly harsh, Jorginho is underwhelming.
Under a different system and manager, he could rediscover his Napoli form, and really help us control possession, but this has to really be calibrated carefully. He needs to come in as one of a number of midfielders.
I have said it before, Jorginho next to Xhaka and let say Ceballos, and we go nowhere. He and Xhaka would be laughably bad together as a double pivot in a 4-3-3.
Maybe together in the 3-4-3 they would be okay, but the idea was to try and transition back to a 4-3-3. Jorginho doesn’t do that by himself.
