I don't think Manchester City and Chelsea are on the same level. Manchester City's defense is just poor this season; they conceded lots of goals and failed to prevent their opponents from scoring, which is why they lost an important point; otherwise, they have strong finishers who can convert chances into goals. If a team's defense is weak, it will be difficult for them to win games, regardless of how many goals they score.
Chelsea, on the other hand, look weak since their attackers have failed to convert chances into goals in the past few games. The Chelsea manager relied on Palmer as if they weren't going to play many games this season, and it's obvious they can't survive when Palmer is out of form. If he had given other midfielders opportunities earlier in the season, they wouldn't have been struggling to score with Palmer out of form.
Chelsea and City started this season differently, but in the end they are close in the table, the difference is only one point, and the fight for the top 4 will now be between Chelsea, City and I think Newcastle. I read today that Haaland may leave City if they are not in the top 4, I don’t know if this is possible because he just signed a new long-term contract, I think he meant that it is essential for City to get into the top 4, and Guardiola understands this well, otherwise he may even lose his place in the team.
