I cannot agree with you. Real Madrid were very lucky to win the title last season. At the same time, Benzema's consistently good performances helped Madrid win the Champions League title. But this season Benzema's fitness is not good. He is unable to stay with the squad due to injury. I think Real Madrid will be eliminated in the semi-finals.
Luck can't make them sequentially beat PSG, Chelsea, and Manchester City who were the most nominated teams to win that title, what helped them is the winning mentality they showed. This season, I think Real Madrid is far from the competition, Manchester City with Halland and PSG with all their stars seem to be the strongest and most passionate teams. However, we should look at the winter transfer market before making a prediction, with the World Cup ended recently, the market this year should be on fire.
I'm really surprised how much in football there is talk about luck as the main reason for someone's success or when someone's victory cannot be explained on the basis of rational statistical data.
If you followed the news from the last 2 world championships, you could conclude that Croatia is the luckiest national team in the world because they were second and third in the world mainly thanks to crazy luck and not the quality of the team.
In a similar way, many neutral observers concluded that Real became the champion of Europe this year thanks to crazy luck, because they deserved to lose from their opponents many times, but they miraculously won every time.
Both of these are actually underestimation of the great and well-deserved successes of Croatia and Real.
Both Croatia and Real had the X factor in those matches, something that their opponents did not have, and which helped them to win.
That factor X is difficult to explain, but it is the reason why Manchester City and PSG have not been able to win the Champions League for years, even though they have more money and better players than Real, and Real has won the Champions League 5 times in recent years, if I remember correctly.
Factor X could be explained as a firm belief that you will win even though everything is against you, complete self-confidence and faith until the end.
