Exactly, that's the part he didn't really get, winning or beating PSG in the finals doesn't automatically give the title to EPL or Chelsea being the best team in the league or in Europe. I'm not undermining the ability of Chelsea but for you to be the best it's not decided by one match but several matches. PSG was said to be the best team last season because of the several big team they came across and won them all to emerge what we call them today.
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.
