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.
Today’s game will be so amazing to watch, seeing Manchester City against Chelsea. Although it will be so hard for Chelsea to win the game, everyone knows that, but I believe Chelsea will come with a great effort of defence that Manchester City won’t find it hard to penetrate because Manchester City will try their possible best to be top in the table, making Liverpool the second, although it is just a 2-point interval between them. I am sure Manchester City won’t play in this game, but they will try as much as they can to gain some points, even if it is 4-6 points, so that they can somehow be a distance from Liverpool in points, so we will wait and surely anticipate the games today and see the scores and how the game will go. Maybe Chelsea might have luck on Manchester City, but it will be so surprising. Although Chelsea always finds it simple to win teams that are stronger than them, I don't think it will work for Manchester City.
