The underdog should now be considered secondary in terms of ability. Chelsea were a relatively weak team, that's true, but now they are in a strong position and beat PSG 3-0. It was impressive and great football for Chelsea. They used simple tactics against PSG and used Cole Palmer and João Pedro, who were in great form, correctly. I myself did not expect them to play such good football and win the trophy. I think Chelsea will gain more strength for next season and will be able to build a strong wall in the coming times, inspired by this trophy win.
I also didn't expect Chelsea to be so strong in the final because before the match, Chelsea were really doubtful about being the favorites. But I was quite surprised when Chelsea were able to play a different rhythm in the final, causing PSG to lose their way because their tactics were completely out of whack. And if Chelsea can continue to do this next season, perhaps Chelsea will be a strong candidate to challenge for the Premier League title, as Chelsea will certainly be looking to buy several new players in this transfer window.
