Many people like to claim that Nadal has done much more in his career than Federer because he has 6 slams by the age of 23 while Federer only had 3 slams (freshly turned 23). Here's a couple of things to keep in mind: -Federer was a late bloomer. He didn't begin his domination until late -Nadal was an early bloomer. He began his domination in his teens Still, many people still believe that Nadal is still much, much faster than Federer. Here are some numbers then: -Nadal turned pro at age 15 (2001) -Federer turned pro at age 17 (1998) In his 8 year long career, Nadal has accumulated 6 slams. Federer, in his first 8 years (being fair to Nadal here), accumulated 7 slams, and this is not counting all of 2006 because we are still in 2009. Therefore, Federer had more slams than Nadal at this point in their careers. The only difference was that Nadal turned pro at an age 2 years younger than Federer. Also, Nadal had his breakthrough in his 4th year on tour (first GS title), while Federer broke through in his 5 year. Both men won their first MS titles in their 4th year. If anything, Federer and Nadal are pretty even, with Federer having a slight edge in slams while Nadal has a slight edge in MS titles. But, the bottom line is, Nadal's achievements at this point in his career do NOTcompletely overshadow Federer's achievements at the same point in their respective careers.
