Greg Rusedski spoke about the relationship between Novak Djokovic and Roger Federer. Speaking about their relationship, in the context of Federer's round-robin match against Djokovic at the ATP Finals in November, the British pundit said: "They don't get on great so Federer would have loved to stop his run at the year-end No 1.
We can never discount these great champions and what they can produce. Everyone was saying it was going to be one-sided and Djokovic was going to win. But Federer showed us why he is such a great champion and you don't normally see that celebration from Federer.
On top of that Rafa was delighted because he had clinched the year-end world No 1 title. If you look at Nadal he has never won this event (ATP Finals) so he would have loved to have won this title. If we talk about Roger Federer, what an accomplishment at his age to be there."
Rafael Nadal feels proud of his, Federer and Djokovic's longevity. The Spaniard recently said: "That's something special, that situation. Since 2005 I have been more or less in those positions. Since 2007, Novak, Roger and I have been in the same positions for such a very long time.
I think if you ask Roger or Novak or myself what we think about that, we'll say it's something very difficult. But here we are. For us, that's good news."
