Manchester City already has a very capable squad in every line, and it's true that they only have to add a few players to maintain a good appearance during player rotation because of their busy schedule and that's what they are doing now and one example is their attempt to bring in Calvin. Philip from Leeds United.
and for a star player they have managed to bring in Haaland from Dortmund, that's already very good for them next season I think.
But with the news that Gabriel Jesus and Raheem Sterling are expected to leave Manchester City, this is a separate note for Guardiola, at least this team must find a solution to overcome the void if the two stars are indeed going to leave City. Plus, it's confirmed that Manchester City will lose Defensive Midfielder, Fernandinho. So far I have only seen two players who officially joined Manchester City Haaland and Ortega, Guardiola must immediately find a replacement who has left, because their rivals Liverpool are making improvements this season.
For record sake and to say, Manchester City is very complete in their squad, even if Sterling and Jesus leaves the club there is still right wing Mahrez, central Haaland and left wing Fodan to take the lead. Other good players including Grealish is still in the team. KDB is always there for reinforcement.
The issue I'm seeing in the squad is the alleged departure of Fernadinho, if the movement is to happen, Manchester City will need a good defensive midfielder to scale the season.
