Separate games mean nothing. Maybe PSG was exhausted by the previous games plus everyone predicted an easy win for PSG and this led to the burnout of the PSG players. But even if Chelsea is really stronger than the best team of the season at the moment, this does not automatically mean good prospects ahead. Bookmakers quote Chelsea's chances of winning the title as 1 to 13. I think you will agree that against the background of City, which went into crisis, the fresh champion and Arsenal, which have passed their peak, this looks like a very weak quote.
That’s not an excuse at all, I think they were outclassed at their own game and prime and no excuses for it. Congratulations and well done to Chelsea for being able to win that game despite the odds that were against them and finally redeeming the EPL from humiliation from a farmer’s league side lol.
