Milos Raonic says the GOAT race between Roger Federer, Rafael Nadal, and Novak Djokovic is 'not only about Grand Slams.
Nadal won the French Open earlier this month to pull level with Federer with 20 Grand Slam titles each, three more than Djokovic has amassed so far.
That has seen debate intensify among fans and media about who tennis' greatest of all time is, but former Wimbledon finalist Raonic believes it is a much bigger question than many are trying to make it.
"It's hard to debate it now because there is a lot of open ended things," Raonic told the press in St Petersburg.
"You have Rafa who's hopefully going to be around to play more tennis. You have Roger who's going to be coming back next year to play more tennis
"You have Novak who's got age on his side and has definitely been the healthiest of them, especially over the last few years.
"It's not only about Grand Slams. Weeks at number one matters, head to head results against each other, how many Masters series you win - there's a lot so there's always going to be an argument about who's the greatest of all time.
"I think we are all very lucky to have that argument all in the same generation where you can compare all these guys rather than comparing some players from now to players from 20 years ago to players from 40 years ago.
"It's really a pleasure to have the guys in front of you all at the same time so you can have that comparison."
