These injuries are due to them being overworked due to the current schedule. They have games after games, International matches, Cup matches and European League matches if you are from a good team, which Kevin De Bruyne is. Oluwa-btc, So you saying Kevin De Bruyne should be sold is literally absurd. Due to him being injured, Manchester City is really struggling. He, Rodri, and Haaland are the 3 key players I see in Manchester City's squad right now.
So many teams are currently suffering due to a big injury list, Real Madrid, Manchester United and so many more. Some players are injury prone and these tough schedules just multiplies chances of them getting injured. So a team should have a backup ready for the key players just in case they get injured and should be rested properly for the big matches to come.
Erling Haaland, Doku and Rodri are all overworked you feel me? But they don't pick up these injuries just like Kevin De Bruyne. Last season he was also absent but thanks to the availability of IIkay Gundogan, Bernado Silva and Mahrez who made sure of creativity within the club. This is my opinion on the Belgian International. City would not want that though, they're a side with lots of funds to get a replacement for him. Absurd? Say whatever you like, that's your opinion.
Go check how these players get Injured and compare you man with em. Kevin De Bruyne Injury alone affects the club and everything. I don't have lots to saay.
Even if you are right and Mancsher City had a bad performance because of their player Kevin De Bruyne getting injured, I still think they had to have an alternative player in the same level to help the team in this situation and that's not good for a team like Manchester Cty to be dependent to a player like this.
Regardless of that, I'm waiting to see how Manchester City is going to perform in the Champions League after Kevin De Bruyne got recovered when they won't have any reason for the weak performance in the team.
