I can't say if Chelsea has improved in their performance or not, it's when the new season starts is when we would know. However, their performance in CWC is impressive and their fate will be tested in the finals when they play against PSG who have destroyed and humiliated top big clubs in various leagues in recent times.
Chelsea have no doubt been impressive since last season when the season was about to end. We saw them also booking a spot in the champions league for next season which is a good progress for them from playing in the conference league last season and winning the trophy, to playing in the champions league next season.
Chelsea has also given us the best of performances in the club World Cup which makes us to have trust in them once more to have improved from the way they use to be few seasons back. The final will really test their strength and even if it doesn’t go in their favour, they look to be back in form with consistency.
Chelsea has been on the improvement and I can say that they have been lucky too because even if they don't play that fantastic yet results seems to go there side but they will be facing a great opposition in PSG that has been ruthless so let see how lucky can Carry the because this game is not going to be an easy one for Chelsea
