Ever since Roger Federer [Images] beat Pete Sampras in the fourth round at Wimbledon in 2001, he has been hailed as Sampras' successor on grass.

Five years since, Federer is threatening to topple Sampras as the best modern-day player, ever.

The American, when at his peak, looked like a one-in-a-lifetime player. But it took only 10 years before Federer was born.

Australian legend Rod Laver, the only player to win all four Grand Slams the same year twice, thinks Federer can win a Grand Slam of titles.

Andre Agassi [Images], after the 2005 US Open final, proclaimed that the Swiss was the best he had ever played against.

At 24, Federer has seven Grand Slam titles. Sampras retired with the most men's singles Slams in history --14.

ATP released statistics that show their amazingly similar career paths, separated by exactly 10 years.
