Roger Federer could be usurped by Novak Djokovic not just in terms of Grand Slam titles but in where he ranks among the greatest tennis players of all time, according to the Greg Rusedski.
“He’s doing things that other players haven’t done before,” said Rusedski.
“We always talk about Federer and Nadal, but this guy Djokovic has a real shot to go down in history and possibly as the greatest to have ever played the game.
“He’s only six [Grand Slams] away from Federer and at the pace, he’s playing right now, there’s a real chance.”
The draw of the ATP Finals groups means Djokovic and Federer could meet in the final, with the two top seeds on either side.
