MELBOURNE (Agencies) Andy Murray and Novak Djokovic set for title showdown in the Australian Open Tennis Championship here on Sunday (today). The two men who have come to be considered the best of the restthat is, after Roger Federer and Rafael Nadalwill face each other for the first time in a Grand Slam. One will walk away with the title. It may seem as though its been a long time coming for Djokovic and Murray, who in practice sessions and pickup soccer games this year have rekindled a friendship first struck when they were gangly preteens on the tour. Thats due in part to the dominance of Federer and Nadal, who between them have won 21 of the past 23 majors. As consistently high-ranked players Djokovic is No. 3 and Murray No. 5they invariably start on opposite sides of the draw at majors, and that means they are almost certain to bump into the No. 1 or the No. 2 before they meet each other. Djokovic beat defending champion Federer in the semi-finals and an injured Nadal was ousted in the quarterfinals by David Ferrer on the other side of the draw, leaving the door open for Murray. Sundays final will be the first time neither Federer nor Nadal have played in a Grand Slam final since the 2008 Australian Open, when Djokovic defeated Jo-Wilfried Tsonga to win his first major. They have been so dominant, such a strong two tennis players mentally, its just been fantastic to watch them dominate the tennis on one hand, Djokovic said Saturday. On the other hand, it was frustrating because you dont have the opportunity of maybe winning more Grand Slams. But over the years playing against them, you kind of get to know them better and start believing in yourself more that you can win. I think right now there are a couple players that are actually believing they can win against Rafa and Roger. With one major trophy already on Djokovics shelf, the stakes on Sunday are higher for his friend. Murray, who jokes dryly that he is considered British when he wins and Scottish when he loses, is being watched by a United Kingdom that has been waiting almost 75 years for a new mens singles champion. Sunday might be his best chance. Djokovic and Murray, both 23, have played each other seven times on the mens tour. The Serbian won the first four, but Murray has won the last three, all on hard courts. The two men, born within a week of each other in May 1987, first met in juniors at 11 or 12, when Murray won in straight sets. They played a few more times and got along well, even teaming up for doubles, when Djokovics basic English skills and Murrays thick Scottish brogue made communication difficult. Back then, we were speaking kind of more with the signs, you know, hands and legs and stuff, Djokovic said. They took different paths through Europe to the professional tour, Murray training in Spain while Djokovic went to Italy and Germany. They met for the first time on the mens tour in 2006.
