London: Novak Djokovic has admitted he can "tolerate" tennis' top stars breaking the rules and communicating with their coaches on court. The reigning Wimbledon champion accepted "we can't pretend it's not happening in tennis" in claiming every top star breaches governing body rules forbidding coaches instructing players in the middle of matches.

Coach Boris Becker has revealed Djokovic's back-room staff "have our ways" of signalling to the Serbian on court "to tell him it's good or it's bad". The 28-year-old himself rejected suggestions his on-court communication with his coaching team represents significant rule breaches.
