I have some doubts about Man City after looking at their transfer market, a lot of key players have been let go like Mahrez recently joining the Saudi Pro League. For sure they need some time to get into top form after so many changes in their main squad.
There have been a number of players out of Manchester City during the transfer window but I don't think they will be lacking for much as there are other players ready to take their place. Kyle Walker, Ilkay Gundogan, Riyad Mahrez are some of the players who won't be with Manchester City next season but look at their squad instead talk about the many drops.
Manchester City still has a luxurious squad even though they have lost several senior players. The team will be regenerating its squad with younger players instead of keeping a lot of older players like Gundogan, Walker and Mahrez, so I think it's a positive change.
