I wish I hadn't said that After Andy Roddick mocked him at the 2008 US Open because of his many ailments and injuries, Djokovic told the crowd: "Andy was saying that I have 16 injuries in the last match, so obviously I don't, right? That's not nice." He was jeered by home fans for the rest of the tournament.
Oolitics A fierce Serbian patriot, Djokovic made a speech four years ago via a video link at a rally in Belgrade protesting about Kosovo's moves towards independence.

I wish I hadn't said that Murray joked, during a joint interview with Tim Henman in 2006, that he would be supporting "whoever England are playing against" in the World Cup. Ever since then he has had to deny suggestions that he dislikes the English.
Politics Keeps cards close to his chest. When asked last year for his opinion on a referendum in Scotland, he replied: "That's a fairly loaded question, I think. I'll step past that one. No comment."

Staying calm before a match "I watch TV, comedy TV, I would say. But I don't go to a temple."

Friendship on hold
Following similar paths as teenagers, both players trained in foreign countries – Djokovic in Germany and Murray in Spain. However, the fierceness of their battles means friendship is on hold.
As Djokovic put it: "I really like the guy, but how can you be best friends with a guy who you know you are going to be doing battle with? For now, we must keep a professional distance."
