Interestingly, it is not yet clear what changes Man City will make... Apart from the fact that midfielder Phillips is coming to them from Leeds and that Jesus is moving to Arsenal... I understand that no top players will appear at the club by the new season, and the main players will also remain with the team unchanged...
Only Erling Haaland has been a top player signed by Manchester City this season and some other transfer rumors I think are just adding players to keep up with the busy schedule and a player like Phillips of course it will be very difficult to get into the main Manchester City squad.
The squad that Man City has is very good and they just need to add a few back-up players to maintain good team play during player rotations.
