No chance for Gundogan to replace Silva. He’s neat and tidy but is much better sat deep where he doesn’t have to make decisions. He’s terribly indecisive when it comes to making that final pass on the edge of the box - something Silva’s always excelled at.
Would that not mean that Gundogan is the natural Ferd replacement? Honestly from the outside looking in I'd say: give Stones another year while playing Laporte and Otamendi. Full backs with Mendy back pick themselves. Maybe grab Javi Martinez for the Ferd role and use Gundogan as a De Brunye sub. Get a top class striker and let go of Aguero (might not be popular with you but he does get injuries a lot) and allow Jesus to keep developing with the pressure off. Promote Foden as the back up to Sane.
Maybe you need another CB but honestly your squad is at a great level, that's why we need so many signings. Hopefully we can put it up to you guys next year, for me it was actually our performances against sides we were expected to beat that killed us off.
Overall get a couple of players to add to the squad but don't buy anyone who will break up a team that steamrolled the League and IMO were quite unlucky/naive against Liverpool in the CL (this happened to us under Fergie in the early years and will come with time).
PS: I'm too lazy to keep trying to spell Fernandihno (hope this is right!).
For United: you guys have been fortunate in certain players reaching a good level. The likes of Janujaz, Depay and Shaw had that top level talent but for varying reasons they never made it. Martial (who I hope stays) and Rashford still have to show it consistently.
In terms of City and United,I don't see a massive gap in quality (although you shade it overall), but I feel the biggest thing that defines our next year is Jose finding an attacking coach that can 'free up' our attacking players and allow them to play to their potential.
I still fancy you guys to finally defend your title but next year should be very interesting, especially with you'd assume a better Liverpool, Spurs, Arsenal and particularly Chelsea.
