I also hope Chelsea can provide fierce competition in the Premier League next season and also in the tougher Champions League. With Chelsea's current abilities, I truly have no doubts that they are a solid team and have the talent to defeat tough opponents. Chelsea could pose a threat to other teams in the Premier League next season, as they have changed significantly recently, leading to their victory in this year's Club World Cup.
Now that their confidence is starting to rise especially after Enzo managed to deliver trophies in the Conference League and CWC then there is certainly a new hope for them in navigating the season that will indeed start next month. At least for the start of the season, their mentality is already established, they just need to add a little spice with a suitable attacking scheme and line-up.
They already have good capital at the moment but of course the season will clearly not be easy considering they are also still in a state of transition especially since they still have to make improvements to support the performance that will not end in a bad thing.
Currently for the EPL Liverpool are still in a condition that does allow for favorites when talking about probabilities, besides that I think Manchester City also although last season was bad they should not be viewed skeptically because their chances are still quite large especially since they have brought in several additional players to support their performance next season.
