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.

Andy Murray turned down other top male and female stars before agreeing to coach Novak Djokovic, Andy Roddick has claimed. And the former US Open champion reckoned the working relationship between the “big tennis nerds” will work because it will not be an “overwhelming commitment” for the Scot.

The tennis world is exploding with excitement after Saturday’s bombshell announcement that Andy Murray will become a coach to Novak Djokovic. Murray officially entered retirement in August – and while he made no secret of his desire to start a coaching career – he was adamant that it would not come soon as he wanted to focus on spending time with family.
