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 doesn't really mean much on the long run. It is obvious that you can't just bet on the favourites every single game, because favourites do lose. If it was that simple, then we would all be super wealthy right now, how?
Well, when the leagues start, every weekend, bet on the favourites on all the leagues, anything that is under 1.70 for example, so it should be a "sure thing" and you would win, because favourites end up winning every game. But that doesn't happen does it? Favourites lose all the time, and this was just another example.
But by same logic, you can't also bet on the underdogs, if it was easy then same logic would say go bet on anything that says 3.00 or more, so underdogs for sure, and then you would lose that too.
Sportsbetting are falling into gambling category for a reason, you take a risk, and sometimes you win, sometimes you lose.
