Yes, I would never have expected such a good performance from Chelsea either. I have to say that it was surprising and very, very interesting to see a team like that score so many goals against a team like Paris Saint-Germain. Cole Palmer is a truly extraordinary player, however.
I have done some analysis before the final and came to know that PSG has conceded only one goal in 6 matches of the tournament before the final and that shows they don't have good attack but also good defence. Chelsea finished 4th in last season of EPL and no doubt is a team that has the potential to beat any team in this tournament but no one expected that Chelsea will beat PSG in such a manner. I am still unable to digest the result of this final.
Many congrats to Chelsea and its fans for such a comprehensive victory over favourite team of the tournament.
