One mental breakdown and a country loses the opportunity to lift the world cup.

If something similar happened to any other player, his career would likely end right then and there. It takes a lot of courage to come back from something like that. It can completely destroy you emotionally and the fact that Ronaldo not only returned but also starred en route to World Cup glory speaks volumes
