Tennis legend Andre Agassi believes Rafael Nadal is very close to surpassing Roger Federer as the greatest player of all-time, adding the Spanish tennis sensation has now the accomplishments to prove he's the best to ever play the game.  

Agassi, who shares with Nadal the distinction as the only players to complete a career Golden Grand Slam by winning all four majors tournament along with an Olympic Gold medal in men's singles, thinks Nadal now has an argument for him to be called the greatest of all time.

Agassi engaged in furious battles with fellow American Pete Sampras and he's convinced his rival was the best tennis player during their era. However, he thinks Federer took his level of play a notch higher with his dominance in all kinds of surfaces.

"Pete was the best of his time. I think Federer's a class above. Pete was off the hook on the faster courts but during the clay season players wanted to play against him," Agassi told Tennis X.com.

Then again, Nadal's emergence as an all-around master following his sensational campaign towards his second U.S. Open Championship win made Agassi think the Spaniard also has a valid claim in getting the lofty title.

"I personally think that Nadal has an argument to make for the best of all time. If Nadal is sitting at a table with Federer and Federer says I'm the best ever, my first question would be, 'How come you didn't beat me?' I beat you twice as many times and by the way, I won everything including the gold medal and Davis Cup," Agassi said.

On the other hand, Agassi believes Federer has done great things on the court more consistently over a long span of time, an achievement which the Hall of Famer considers very impressive.

"But at same token Federer has separated himself for a few years like nobody else and he's done it more consistent. To be able to make the argument for both guys playing in the same generation is pretty remarkable," Agassi added.
