#1 Ronaldo - Brazil - Seizures before the match
The former Ballon d'Or winner has had a splendid career not just with his national side, but also with clubs like Inter Milan, Real Madrid, and Barcelona. His performance as a world-class striker has earned him some of the most prestigious comparisons with football legends like Pele and Marco van Basten.
One of the most feared strikers of his generation, the World Cup winner made sure that he delivered every single time he stepped foot on the pitch.
However, a fact that isn't known by many is that the Brazilian legend just hours before the 1998 World Cup final reportedly experienced a 'fit', that had foam erupt from his mouth. He was forbidden to play by the doctors, but as his passion for the sport spoke through his actions, he did show up at the finals.
Though, Selecao ended up losing, they did respond to the French side 4 years later. As mentioned earlier, he was not cleared to play, and as a result, this fact generated a lot of controversy in the media, stating that Nike forced the Brazilian to play. However, both Ronaldo and Nike denied all the speculation.
