MACAU (China) (AFP) Roger Federer trumps Rafael Nadal as a tennis great despite the Spaniards stellar season, world number five Robin Soderling said in Macau Saturday. The Spanish number one became the seventh man in history to achieve a career Grand Slam as he earned his first US Open title with victory over Novak Djokovic in this months final at Flushing Meadows. The 24-year-old Spaniard has notched up nine major titles leaving him seven behind his Swiss rival, whose tally of 16 Grand Slams is the most in mens tennis history. Soderling has lost to both players in consecutive years in the French Open final but said despite Nadals completion of a career Grand Slam, Federer, currently the world number three, remains the yardstick for mens tennis. Hes won so many Grand Slams already, so many titles but to me, Roger is still the best. But Rafa is still very young so if hes going to be healthy, he has a lot more years to play and he could definitely give it a shot. He has the chance to be known as the worlds best player ever, added Soderling, in Macau for an exhibition tournament featuring three other players ranked in the top 11 Nikolay Davydenko, Tomas Berdych and David Ferrer. World number seven Berdych, who beat Federer in this years Wimbledon quarter-final only to fall to Nadal in straight sets in the final, said the Spaniard had enjoyed a stellar year. Its not easy to win three Grand Slams (French Open, Wimbledon and the US Open). Still, I think its a lot to go for him to get the best player so far in history but hes a great athlete and a great person. And David Ferrer, world number 11, said his fellow countryman, although the best player in Spains history, could not yet claim to be the greatest ever. I think Rafa is the best player in history for Spain, he said. But in this moment maybe its Federer because he has more Grand Slams and more titles, he said ahead of Sundays Venetian Macau Tennis Showdown. Nadal and Federer have won 25 of the past 30 Grand Slams, setting a blistering pace that the rest of mens tennis has failed to match. But Berdych said: For me, its a good time to be in this era that you can be competing against these two great players. Of course, you can see it from the other point of view that maybe if these two guys wouldnt be in the draw, in the tournament maybe it could be a bigger chance to win a Grand Slam.
