Because the season is still very long for all teams, including Chelsea, the Chelsea manager clearly needs to improve tactical stability and team strength. Chelsea also needs to excel in the Premier League and the Champions League, as several Premier League teams are also participating in the Champions League next season. However, it would be very surprising if Chelsea could go far in the Champions League and even become a title contender in the Premier League, although I still have some doubts that Chelsea can achieve that this season.
It may be a tough challenge for Chelsea to win both the Premier League and the Champions League. However, in football, surprises often happen. Chelsea's success depends on their ability to handle pressure and adapt to the situation on the pitch. If they can maximize the potential of their young and new players and unite them into a solid team, it's not impossible that they can perform more than our expectations.
I think Liverpool, Arsenal, and Manchester City have a better chance of going further in the Champions League than Chelsea. Of course, Chelsea has a lot of experience, having won the trophy twice, but with a very young squad, it will be very difficult to be a trophy contender in the Champions League. Enzo Maresca will probably be realistic and have his team prioritize winning the Premier League trophy first.
The competition for the trophy will be much more competitive than last season, and I think Chelsea also still has to adapt to the new Champions League format, especially in the league phase, which even many elite teams find difficult. Chelsea success in the Club World Cup might encourage them to play with more confidence this season, and at the same time, it confirms that they are now a team to be reckoned with again.
