They boast the greatest rivalry in major tennis history - the only two men to have clashed in all four Grand Slam finals - and now the stage is set for a sequel to their epic six-hour Australian Open decider in 2012.
Ladies and gentlemen, presenting Rafael Nadal and Novak Djokovic, the two tennis gladiators set to deliver a Melbourne Park encore two years in the making.
After missing last year's Open with more knee troubles, Nadal is back for the season-opening slam as world No1 thanks to an extraordinary 10-title return in 2013.
The Spaniard relieved Djokovic of his top ranking with tour victories in Sao Paulo, Acapulco, Indian Wells, Barcelona, Madrid, Rome, Montreal, Cincinnati and Grand Slam numbers 12 and 13 in Paris and New York.
Nadal won indoors and out, on clay and cement and, during one particularly relentless run, 62 of 64 matches in a spectacular, record-setting $15 million season.
