You are not alone bro, I was also shocked by the outcome of the result. What shocked me most is how Chelsea as was able to prevent PSG from playing completely, dominated the play and even hid key players such as Dembele whom I can count how many times he touched the ball for the 90 minutes of play. It was really embarrassing for PSG yesterday because as the champions of Europe, they ought to have given a better performance than that fatigued display they showed.
I think everyone was surprised to see the outcome of the game after hyping PSG and praising them for all they have been doing but at the end when they were expected to complete the work Chelsea came and give them a total different defeat much more than we expected. Chelsea players outplayed the PSG players they pocket the players that were expected to score for PSG that's why we couldn't see them play their football.
The confidence of PSG fans and those who bet on a PSG win was immediately shattered after the first half ended 3-0, fortunately Chelsea did not increase their lead in the second half. This result proves that many things that were considered impossible are possible, there is no team that cannot be defeated because anything can happen in football.
Chelsea played better than PSG and this success was due to the ingenuity of the coach who was able to formulate a good strategy to dampen the toughness and sharpness of PSG front line.
