Not quite! Last season, few bet at the beginning of the Champions League, that Chelsea would be the champion.
By the way, not even when they reached the final, many were not expecting Man City to lose the final against Chelsea.
There are no pre-announced winners. There are top favorites for victory. Since a lot can happen, and a favorite club may cease to be, and a club that is not become, over the course of the season.
This year, like last year, PSG are among the favorites to win, like Man City, Liverpool and Bayern München. One of them will be the winner, or we may have another surprise.
