I don't know what you all are thinking but from my point of view Manchester City team has started this season very badly than last season. Last season had a fantastic performance which deserves praise but the team's performance has suffered a bit since Kevin DeBruina left the team due to injury at the beginning of this season.
Although there is a slight difference in Manchester City's performance at the start of this season, I think it is very inappropriate to judge Manchester City to have been bad at the start of this season. Because everyone can see that after seven matches at the start of this season, Manchester City is still ranked first and that can be very accurate evidence that Manchester City has not been that bad at the start of this season. In fact, Manchester City will still be a candidate to win the Premier League this season.
It does not matter with a good start in the last season and maybe a poor start in the current season because anyway, that Manchester City remains the superior team. Therefore, although Manchester City have suffered one defeat this season but still, Manchester City are still at the top of the Premier League table and also, Manchester City are also undefeated in the Champions League in the current group phase . So yes, it is not right if you might consider Manchester City to be weak just because of De Bruyne injury. Because anyway, even though De Bruyne is injured but the fact is Manchester City can still compete well too, so De Bruyne injury will certainly not make Manchester City bad.
