In addition to the Club World Cup, they also won the Conference League. I already know what you will answer, that it is not a very prestigious tournament and the opponents there are not the strongest, but then they won the Club World Cup, so winning two tournaments in a season is already a good indicator and excludes any accidents. Chelsea is a good team, and in the new season we will be able to evaluate their strength in the Champions League and the Premier League.
hopefully that happens to Chelsea in the Champions League and Premier League for the next year, to be the best among other clubs. even so the possibility can can't be unpredictable because there are many factors that must be fixed within the team, including the mentality of the players themselves, and Chelsea has tried to reach that level and Maresca is trying to make his team the best.
