Maybe you have to accept that the league is not only between these teams but also between other teams such as Chelsea Football Club.
With so much success and so many triumphs of this team in the present, is it reasonable to forget that the upcoming tournament is limited to just those three teams? Currently this team is probably going to be a big favorite for next season as we realized that they have just returned from winning the CWC tournament. However my idea it is true that Liverpool and Arsenal Football Clubs have a lot of good things to do and they can still be bet on for the upcoming season.
I'm not moved by Chelsea. They won the Club World Cup and beat PSG in the final, but that doesn't mean they can be able to win the league. They may win other trophies like the FA Cup or Carabao Cup, but the league is something different. League is a different competition from tournaments. A tournament is a knockout competition where any mistake can take a team out of the competition. The league require more consistency. You have to be good on every match day and ensure you remain at the top, because other teams are also doing the same.
Also, in the Club World Cup, Chelsea did not meet a top team till they met PSG in the final, and yeah, they were very good in the final, but that doesn't mean they are that good.
Also, it was expected of Chelsea to win the Conference League. It would have been very disgraceful if they didn't win it because they have spent way more money than every other team in that competition, and they are the biggest club there. This may not be something Chelsea fans will like to hear, but it's my opinion. Chelsea doesn't look like a team that can win the league.
