I think the best thing about the derby win is that they spent a fortune on Pogba and he was torn apart by our two man central midfield pairing of Fernandinho and Silva. He didn't get involved. Zlatan didn't appear until they played hoof ball in the second half. Their best player was a young kid Mourinho has stuck on the bench for the most part this season and only when he came on did they threaten with the ball on the deck. They still don't know how to play their best players because Rooney can't be dropped and he completely damages their team. They've got the likes of Mata and Mkhitiryan who could create chances but Rooney is occupying their best position.
Meanwhile Silva is playing as a central midfielder and dominating games. That allows De Bruyne to play as a no.10 and a fluid attack with Sterling and Nolito. We've bought players and we know where to play them. Stones has slotted in well and Bravo will too once he's had more time with our defenders and the communication is sorted. Gundogan is probably the best midfielder in the league and he's not even come into our side yet. Gabriel Jesus looks a class act and right when you need to kick on after a busy festive period of games, he'll be able to slot into the side and will cause the opposition no end of problems.
