I'd say an 7.5/10.
Gvardiol & Kovacic have fitted in seamlessly and Doku is an incredibly exciting signing. I do like Nunes and think he has a good skillset for City, but I think his flaws are what you expect and settle for in a 4th choice midfielder during a window. The midfield transfer strategy has been a bit odd and a few misses in there. Bernardo extension was great but seemingly odds on for a move next season, which will mean we're looking at a replacement for him and KDB's successor.
I'd rather have kept Palmer - his decision, not the club's and good value - but it felt like this was going to be a big season for him. Foden & Bernardo are better in the middle, leaving him, Grealish, Doku & Bobb as the wing options. The other sales I can get more onboard with - I can't see any other Lavia type mistakes and we have had good value. I hope Borges does well & we resign him. I'm also not particularly fussed if Walker doesn't sign a new contract extension.
All in all, an interesting window that has seen us lose experience & age but replace it with some fantastic quality & possibilities.
