I also had the same thought. Even though Man City's recent performance is not good, but that doesn't mean their chances in the title race are gone. There is still quite a long way to go in the Premier League, so Man City still has time to improve and return to their best performance. De Bruyne has been out for quite a long time, so there is a possibility that he will not be able to play as well as before his injury but still his return will strengthen Man City's midfield and provide motivation for his teammates because he is one of the key players who can make a difference when he has the opportunity to play.
It's a shame when you win 2-0 against not the strongest team and at the end of the match you miss the victory. It was something incomprehensible, why was it so blatant to hit the legs in the penalty area, it seemed like an experienced defender was making such a stupid mistake. City lose points in matches where it would seem that they should take 3 points without any problems, and of course there is still a lot of time ahead, but the competitors will not wait, and then it will not be very easy to make up.
