In 2014, Wawrinka won a five-set quarter-final on his way to a first Grand Slam crown at the Australian Open, beating Rafael Nadal in the final. Last year, Djokovic saw his hopes of completing a career Slam crushed in four sets by the Swiss in the French Open final. At the 2015 Australian Open, Djokovic needed another five sets to win their semi-final. Despite his run to a seventh US Open final, it has not been plain sailing for Djokovic. The Swiss player, so often in the shadow of Roger Federer, has blossomed late in his career, winning the Australian title at 28.
