Robbie Koenig, former professional tennis player from South Africa, has shared his thoughts on Roger Federer’s quest to add another grand slam title in his career. While Koenig doesn’t question how Federer maintains his level and enthusiasm to play tennis, he believes that Father Time will be a big factor in the Swiss’ mission to add another grand slam title in his resumé.

“He (Federer) still believes he can win it 100% - when you’ve done as much as he’s done, then you still believe,” Koenig told Sports 24. “When you get over 30, you get off days and on those off days, you lose, which is not always the case when you are in your prime.”

Federer had a fruitful start to 2015 after claiming 1000th win of his remarkable career over Milos Raonic 6-4 6-7(2) 6-4 in 2015 Brisbane International final. Federer played his next tournament at the Australian Open, where he was one of the top contenders to win the title. However, he suffered a shocking exit after he was upset 6-4 7-6(5) 4-6 7-6(5) in the third round by Andreas Seppi.

Federer's last grand slam final appearance was in the finale of 2014 Wimbledon but lost 7-6(7) 4-6 6-7(4) 7-5 4-6 to Novak Djokovic. Incidentally, Federer won his last grand slam title in Wimbledon in 2012.

Despite not winning a grand slam title since 2012, Federer still leads the grand slam tally with 17, which is the most in the history of tennis. Federer’s rival Rafael Nadal and retired tennis legend are tied in the second place with 14 grand slam titles apiece.

Koenig, who currently works as a commentator for the Association of Tennis Professionals (ATP) World Tour, reckons that Federer’s grand slam record is safe from Nadal at least for the time being. Koenig believes that the Spaniard will find it tougher to continue his domination in men’s tennis and added that other tennis players are going to start believing that they can beat Nadal every time the Mallorca native loses in a tournament.

Koenig said that Djokovic will be the one to keep an eye on in the next three years. However, he thinks that the Serbian will also be unable to get passed Federer’s illustrious accomplishments in tennis.

Federer is set to defend his title at the 2015 Dubai Duty Free Tennis Championships. The tournament kicks off on Feb. 15 at the Dubai Duty Free Stadium.
