I don't think there will be major squad overhaul in the summer..
Cancelo gone, probably Bernie will follow and Gundo as well, but Club may give him +1 year extension like it happened in case of Fernandinho.. And I think Laporte may go as well.. John is untouchable, Ake plays decent football and improved in all departments, Akanji cheap and efficient, Ruben is Ruben... This makes 3-4 players in overall, not a big number..
In terms of additions - 2 new players: LCM and LB..
Maddison is great player, suits LCM role and has all the abilities to play decent football in this City team.. But Bellingham would be a better option, I guess..
As a LB maybe Club will go for overlapping LB to help Grealish on that wing.. Robinson, Chillwell, Theo Hernandez, there are number of options and hopefully we will get as best as possible..
So that's it.. In the end we will have four 30+ players: Walker and Gundo (finishing their contracts in 2024), KDB and Mahrez (finishing their contracts in 2025).. Other ones are below 30 and can play for the next 4-5 seasons for sure..
This season may become difficult due to reason that we don't have replacement for Cancelo, but in terms of future and transfers, I guess everything is OK and well-planned..
Well done Txiki :D
