You are right, from the beginning of the season Manchester city has been in a very terrible form and this isn't the team we once knew...I remember that Manchester city we all believed in, they always delivered when it comes to comeback goals and it was hard for them to get defeated...This new season is actually different for them, I don't know what their problem is and I am not optimistic about them winning the title this year as well
Perhaps the loss of Kevin De Bruyne is one of the reasons for Manchester City's decline in performance.
The player hasn't looked like a key player after a long injury layoff, but he's nonetheless a key player who consistently supports Erling Haaland in scoring the winning goals in every match.
What's happening now is really just about getting the right players to achieve more consistent performance.
While the absence of KDB might be felt, it is not the main reason looking at their team performance even last season when their performance declined.
Now they are just trying to get back on track, new players haven't really gotten used to each other, this is another reason and hopefully the addition of Gianluigi Donnarumma might even make things better for them defensively.
