Novak Djokovic praised Roger Federer in a press conference at the ATP Finals in London. The Serb said: "I have utmost admiration for him and everything he's doing on the court. What he has achieved over the years and what he's still showing on the court is phenomenal.
I mean, he's a role model even for me that I'm one of his rivals and, you know, one of the toughest opponents I had in my career. You know, looking at his career and what he still is doing, it just inspires you."
