This Manchester City we saw so far in this season was far from the good form they had in the past and they were getting bad results. Manchester City is a team they are very much dependent on its players and it seems without some players like Kevin De Bruyne they will have a bad performance and you saw in the last games we saw from Manchester City while they had De Bruyne they got much better results and that's why I think this team is not in the good firm this time and they are far from the good days they had in the past.
Nothing really changed with Manchester city except that they did had a few injured players which were actually their key player even still they haven't had really bad results, they have won a few and also lost a few games too so it's not really rational to think they changed that much, there's a norm with every team when it has to do with players dependency, player dependency is actually inevitable in any team and that doesn't mean without such a player the team will not be able to still perform well but when such players are around there's always a difference in their performance and that was what Manchester city experienced in the past weeks with their form and performance, all along without bruyne Manchester city had won games and still performed well him been in the team is an added advantage for better performance.
The only time Manchester city's form worsen was when doku and haland also got injured that was enough players to affect the team, bruyne's injury alone didn't affect the team that much because they were able to win tough games in his absence, Manchester city isn't a one player dependent team.
