The potential results leading to Manchester City maintaining their lead, albeit by a narrow margin, sounds plausible. The top three teams in the standings maintaining their positions would indeed keep the title race intense and captivating for fans and neutrals alike. But football is a sport with full of surprises, and anything can happen on matchday. anyway, whatever the results, These three teams are going to be three horses race for the title this season, because even if any team lose, the points gap is still so close.
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.
The top three teams are teams that are trying to maintain their performance so far this season and are trying to fight for the EPL title. I'm not too sure which team will be able to survive until the end because they continue to performed well until now and continue to wins to continues to collect as many points.
Chelsea won't be able to stop Man City from winning at home even though in football it can still be surprising but I'm not sure Chelsea can do it. The only thing that can stop Man City is when Chelsea can score the same goal to achieve a draw to share 1 point but I don't think Man City will allow that.
