"Miami Nadal vs. Federer 2004- I remember looking on the internet asking myself who is this kid?!?"
I was lucky to be at that one as well and I thought, wow, this kids 17 (I think he was 17, right ?) and he just beat the #1 player in the world. Imagine that happening today.
I mean Nadal was a prodigy. His tennis was more simple but more based on fitness. But he has such superior genetics. I mean in his teens he was as strong as some adults. Even today. Most people can't take that punishing on their bodies.
And even Federer said that nadal is the future nr.1 at that time. I don't know if it was after this match or after his first match against Nadal.
