Here are the winning chance of each team to become a champion in the next season:
60% for Real Madrid
39% for Manchester City
1% for Arsenal, Inter, Milan, Barcelona, PSG, Bayern Munich, Leverkusen etc.

Real Madrid without Mbappe can still become a champion in this season, so it's no doubt majority of people will believe in Real Madrid.
Yeah it really seems like a joke. Real Madrid is not too strong, they were so lucky on semifinal with Bayern on Madrid (especially on 1-1 goal).
Manchester City? Good on a paper but pitch says something different.
1% for all teams in the world excluding 2 overhyped teams? Really?
The statistics looks ridiculous but that doesn’t mean his statistics is wrong. He did it base on current times and what each of the team are playing and we can all see for ourselves. Until next season begins and we see what it looks like before we can now start making predictions on which team will do better than the other, as of now, Real Madrid still remains the favourites after signing Mbappe and Manchester coming second most likelihood to win the Champions League after Real Madrid. All other clubs will definitely fall within the 1% unless we see a different performance from them when season begins. We want to see a more competitive season than the last one, so every club needs to be at their best to deliver the best to make the competition more enjoyable to follow.
