Looks a quality player. City could well have a very productive summer - if they get in Walker & Fabinho (both seem likely); a left back such as Mendy or Rose and a top centre back (linked with Bonucci & van Dijk) they will be very well equipped for next season. As I mentioned before, previous Pep sides always punished teams with attacking full backs taking advantage of space out wide. They didn't have that option this season given the limitations of their full backs going forward, but looks like they will be a lot stronger in that department next season.
All of the positions/players above United could very well do with - perhaps Walker aside.
