Roger Federer admits he is motivated by claims that Andy Murray and Novak Djokovic are going to leave him behind and dominate tennis.
Federer returned to the summit of the world rankings after winning his 17th Grand Slam title at Wimbledon, but all the betting line talk
is of a burgeoning rivalry between Murray and Djokovic.
Murray claimed a stunning win over the Serbian at the US Open in September to break his Grand Slam duck. Djokovic responded in champion fashion by winning the China Open and Shanghai Masters on his way to reclaiming the number one spot from Federer. He will end the year at the top of the rankings.
Experts have predicted the pair will now dominate the sport in the way Federer and the injury-plagued Rafael Nadal had done for the previous seven years.
Federer believes the emergence of more contenders is good for tennis, but insisted he is not ready to sit back and watch Murray and Djokovic steal the show and is determined to improve his live scores
"Does that suggestion motivate me? I guess. Does it annoy me? No," Federer told the Times.
"It is great for the sport to have a lot of champions out there playing the game and it is natural that they would get more of the limelight for what they've achieved in recent months.
"I always knew that Novak and Andy would stay around at the top of the game for a long time and this [at the age of 25] is the time when they should be playing their best tennis."
Six-time champion Federer will get his ATP World Tour Finals title defence underway when he faces Janko Tipsarevic on Tuesday. The Swiss will be determined to prove he is still the top dog in men's tennis.
