In short, you can say that Chelsea was a more experienced team as compared to PSG, and this thing came to their advantage. PSG weren't comfortable and were feeling the pressure of the final. That is the reason that Chelsea took early advantage in this game and quickly scored three goals in the first half of the match, making the match totally under their control. Palmer scored two back to back goals and gave early advantage to his team.
PSG had such a big semi final game where they beat the giant Real Madrid by 4-0, but in this final they completely collapsed.
Chelsea having more experience than PSG? Cut it mate they don’t, this current Chelsea team might have experienced playing against many of the English top teams but they certainly just didn’t have better experience than the PSG team which has practically defeated more top teams than Chelsea in all competitions. This is like saying Crystal palace had more experience than Manchester City having beating the Citizens in an FA cup final or Newcastle having same than Liverpool too. I can say from the coaching staff to the entire squad PSG boost of more experience than Chelsea.
The Clear difference is that PSG approached the game with so much confidence and Chelsea approached same game trying to prove to the world that they can match any team. For me credit goes to Enzo Maresca for spotting out Luiz Enrique plans and coming up with a very wonderful counter plan which I think was the major factor to the win, Chelsea pressed PSG the way PSG presses opponents which forced them into not playing their usual pattern
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.
This is why this Chelsea win was a very good one and a confidence booster for next season because Chelsea have actually not defeated just any team but one of the most complete teams in the world at moment, this PSG team have a very sold defense with their full backs the two of the best in the world, their midfield the three best in my opinion, the attack is also good. Going into this final the only that changed was the Pacho missing and seriously that wasn’t an excuse, Chelsea simply were at their best and that’s why they won
