Those statistics are real and Real should be the favorites but I do have a feeling whoever will win UCL this year , will be a surprise and personally I don't see Real , City or Bayern actually winning it. Maybe Arsenal ? Maybe Inter or Ac.Milan ? Maybe Barcelona ? I think football needs a fresh team to win the trophy to re-gain the confidence of fans to actually love this competition.
Arsenal?, personally I hope the Gunners can win the UCL trophy. It's just that, I can't describe or predict that they will win the UCL trophy next season. the reason is simple, Arsenal is not quite ready for that. But even so, football is unique and anything can happen, including Arsenal. Even though I'm a Gunners supporter, I'm a little skeptical. Ideally, Arsenal will win their Domestic League first before strengthening their team to compete for the UCL trophy.
Speaking of Bayern Munich, I also doubt it. Moreover, currently Bayern is led by a manager whose performance has not been proven. Barcelona, just like the two teams we mentioned in this post. In fact, until now they are having difficulty recruiting newcomers according to the team's needs. but still, as I said before. Football is unique, we can't just rely on data and statistics. because in a football match there are other things apart from that, or in other words, to predict accurately there is no definite calculation or even formulating luck. Even for Manchester City and Real Madrid, it is not certain that they will win this competition. although, we could say that Man City or Madrid have a higher probability than other teams as competitors who have great potential to win the UCL trophy.
