How many threads will there be about that ?
The most #1 record reached thread
it's far from a certainty : if Nadal wins Roma, Madrid and the French Open, Federer needs to earn 1360
points to keep number 1 after Roland-Garros.
Probably he would need a French Open final for that. And I fear that even if his condition is not bad comparing to previous years, his confidence looks really hurt.
He also needs to get 1300 points more than Djokovic, and well, Djokovic has a good draw here : I don't underrate him.
Note that Fed can lose number 1 after Roland-Garros but take it back after Halle if Nadal doesn't keep on his streak in the Queens. In that case, he would beat this "famous" record.
Anyway, I think if Nadal wins all these tournaments, he will fully deserve taking back number 1
It's normal that number 1 players are young, it's not normal that old players like Federer are : they are only number 1 if the young competitors fail.
Sampras was lucky enough to have a few weeks at number 1 in the end of 2000 because the young competitors were not good enough yet (young Safin, Kuerten). Well good for him
If Federer is lucky about that because Nadal fails, well good for him as well
But the most important is the current situation : Nadal as number 1 would be perfectly normal
