I don't believe in bookies odds especially, when the competition have not started, because there are some factors that can affect the performance of these clubs next season. This was how the bookies gave Madrid the odd of them being the favorite to win this past one, that was lifted up by PSG. I didn't see PSG on this list. Maybe, PSG is in the list of other casinos.
PSG winning the champions league last season was a shocker to almost everyone who witnessed the Victory last season, at the beginning of the season Real Madrid had a very excellent squad packed with good young and talented players so it is normal to think that they will win the champions league, putting them on the list was just an expected thing the casino, looking at the quality of the squad it was okay to put them on the list, they have also won several of the trophies in a row previous season, so it was expected they will make the best attempt or even win the trophy but PSG did. This will help prove the fact that the casinos do not have the ultimate ideas about what the results and outcomes of the games will look like at the end, if you have a better perspective, it is better to follow up with that, rather than depend on the casino.
