The difference in points is not too big because there are still a lot of matches left this season but the problem now is how Manchester City can get out of their slump after Pep Guardiola's team failed to win a match in 4 consecutive matches and even their performance was very bad.
We have seen how Pep Guardiola can always overcome the problems in the Manchester City team in previous seasons so the same thing is also possible to happen this season, so I think it's all a matter of time and Manchester City can definitely rise and return to the path of competition for the PL title this season.
Pep Guardiola may often be able to turn things around, especially when the title race is approaching the end of the season. But it looks like this time it could be different, because Man City has never experienced 4 consecutive defeats in the last 10 years, and it might be that their rivals will be much tougher this season because I think teams like Liverpool and Arsenal have already learned from the mistakes that made them slip at the end of the season. So if Man City can't get back on their feet quickly, I think they will really miss their chance this season.
