Ancelotti won't win in 2030 WC
From a mathematical perspective, Ancelotti won only 24% of the times he competed in the Champions League, with a performance like that only in the 2058 World Cup does he have a chance, of 90%, of winning at least one World Cup, but he will only stay until the 2030 World Cup, that gives a chance of only a 42% chance of winning at least one World Cup playing two editions. It is much more likely that Brazil will lose.
That is me being optimistic and considering that he will have the same performance in the World Cup that he had in the Champions, which is highly unlikely, since it happens every 4 years, Brazil's squad is a joke, he is old and already has trouble thinking of strategies.
It's no wonder that he was fired by Real Madrid recently.
