I hope you learnt something important from that match, take note that no team should be underrated regardless of the odds the bookies give and also in the football world anything is possible, if Leicester would come out of relegation and win the EPL league then nobody should be suprised as how Chelsea beat PSG, that's football for you.
Well, I don't blame those who believed in PSG and better in them, PSG were in a crazy form and so the majority of football lovers apart from hard-core Chelsea fans would definitely believe in them more than Chelsea. Anyways their performance was top notch Chelsea really deserves the trophy, I don't care whether anyone thinks otherwise.
That is another thing in football, odds can be deceiving in a way that even the smallest odd had to lose to a bigger odd and you'd how they hype the team with the smallest odd as the favorite, this style of picking games has made many to lose their bet but on second thought, nobody saw that game as one that PSG would lose and the were terrible to start with. I almost thought some of the PSG play was on suspension or something because they played like something went wrong, no tactics that Enrique did not employed but still Chelsea was on top of their game. I can't say who deserves the trophy because both teams wasn't out there to play but if I'm to say who the winner should be base on performance right from the start of the competition I would go for PSG full time.
