This week the three teams you mentioned still have the chance to win and get full points in their respective matches. Because I'm not sure Chelsea will be able to hold off Manchester City to win at home this week, so the three top teams you mentioned still have the potential to have the same points gap after this week's match. Because the opponents they will meet in this week's match are opponents who are not stronger than themselves.
Manchester City have terrible strength so far, they have managed to get five wins in a row, so for Chelsea, this is quite a tough opponent, and they have to do very high defense. As long as Chelsea can play defensively, it is possible to get a draw, but I am sure Manchester City will try full strength to get a win in this match to increase the points owned by Manchester City and take first place in the standings.
When Haaland and De Bruyne recovered from their injuries and returned to playing, Manchester City appeared very fierce in the match they played, because these two key players played a very important role on the field. In my opinion, Manchester City will definitely play very aggressively against Chelsea, because in this match Manchester City will really benefit from playing at home and will definitely dominate the course of this match. Maybe this doesn't give Chelsea room to get into Manchester City's back line because Chelsea's performance is still very questionable and lacks consistency so they can't survive. Certainly this match will be a victory for Manchester City so they can compete with Liverpool and Arsenal at the top of the standings.
