Novak Djokovic is trying to find new stimuli in the last stage of his legendary career. The Serbian ace has just experienced one of the most delicate seasons of his career, in which he did not win a single title.

Novak Djokovic ’s decision to hire Andy Murray has been branded an “act of war”. The former rivals shocked the tennis world over the weekend, announcing that the newly-retired Brit would coach the 24-time Grand Slam champion during the off-season and Australian Open.

Former eight-time Grand Slam champion in doubles Nenad Zimonjic underlines that Novak Djokovic is "a smart guy" and therefore knows extremely well why he added Andy Murray to his coaching staff for the Australian Open.
