Novak Djokovic stood with his hands on his hips, listening intently to Andy Murray — his longtime on-court rival and now, stunningly, his coach at the Australian Open — between sets at Rod Laver Arena.

Andy Murray should not take the credit or blame for Novak Djokovic’s performances at the Australian Open, according to Andy Roddick. The Scot sat courtside for the first time in the Serbian superstar’s entourage as the 24-time Grand Slam winner won his opening round match here against American wildcard Nishesh Basavareddy.
