Pep doesn't play somebody like Jorginho at the base of midfield though, does he? I know he targeted him in the summer, but I do have my doubts over whether he would have used him in this role.
I don't think City would get away with Silva/De Bruyne without Fernandinho's incredible work rate and tenacity, he's a very complete midfielder. Jorginho may be able to dictate play, but he's useless without the ball (the opposite of Fernandinho) and this makes Chelsea very easy to play through and very vulnerable to the press.
Us, Arsenal and City all played our way through Jorginho very, very easily. It's a massive tactical issue for Sarri and one he hasn't addressed at all.
