I think that Chelsea can do a lot of things this year, we have seen teams especially in the Premier League that are really scary and are super supported by the organized fans who have amazed everyone with surprising performances even if the year before they didn't do much.
Let's see how he behaves, he certainly has what it takes to do well
when he faced PSG he showed that he had the numbers, the people and the mentality to do well
Much depends on how they deal with this fact, whether in a proactive or destructive way.
I don't think we need to dwell on this. While Chelsea's success in the Club World Cup is impressive, it doesn't guarantee a stellar performance in the Champions League. Every team experiences changes, both positive and negative. Therefore, we shouldn't assume that Chelsea are guaranteed to perform well in the Champions League, as they could experience a dip in form that could lead to a poor performance in the Champions League.
Furthermore, Chelsea currently have a busy schedule, which will undoubtedly impact their performance. Therefore, this season will be the one where we can truly see Chelsea's performance. Personally, I believe that if a team wants to win the Champions League, many factors are needed to ensure a smooth process. Among them are a strong mentality and a reliable reserve team. If Chelsea lacks these factors, I don't think they will be able to compete effectively in the Champions League.
