Djokovic and Federer will face off for the 45th time when they clash in the semi-finals in Melbourne after they came through their last eight matches on Tuesday. Djokovic eased past Kei Nishikori 6-3 6-2 6-4 while Federer beat Tomas Berdych 7-6 (7/4) 6-2 6-4.
The head-to-head between the pair currently lies firmly in the balance at 22 wins each but Djokovic has the edge in recent match-ups, winning their last three meetings in grand slams.
The Serbian has usurped his fiercest rival at the top of men’s tennis but Federer, now 34, has had a renaissance, producing some of his best form in recent months and reaching two grand slam finals last year.
“You have to be on the top of your game because he hasn’t really dropped the level at all I think in the last seven, eight years that I’ve been playing against him,” Djokovic said.
“He’s been playing always consistently well. I think his backhand is better than it was maybe five, six years ago. So he’s playing some terrific tennis on the hard court. This is going to be a big challenge for both of us.”
Federer continues to chase an 18th grand slam title, with his last having come in 2012, while Djokovic is trying to close the gap as he sits on 10.
Victory at the Australian Open would move the top seed level with Rod Laver and Bjorn Borg on 11, and Rafael Nadal is also within sight, four clear on 14.
“I’ve played these guys (Federer and Nadal) so many different occasions. I’ve battled them for the biggest titles in sport,” Djokovic said.
“These two guys made me the player also I am today. I think these rivalries have allowed me to grow and to evolve and to understand what it takes to be on the level that they are on.
“They’ve been dominating tennis before Andy Murray and myself came along for many years. It took a while to get in the mix. It keeps going. Roger is playing really terrific tennis in last two years. We played two grand slam finals last year.
Djokovic came out on top when the pair played in last year’s finals at Wimbledon and the US Open, and the suspicion remains that the Serbian, six years Federer’s junior, holds the physical advantage over five sets.
Federer has reached three grand slam finals since he lifted the Wimbledon title in 2012 but title number 18 has so far proved elusive.
“It’s part of the reason why I guess I’m still playing. I feel like I’m competitive at the top, I can beat all the guys on tour. It’s nice now that in the last three slams that I’ve been as consistent as I have been,” Federer said.
“I’m playing good tennis, fun tennis for me anyway. I really enjoy being able to come to the net more like back in the day so I’m very pleased. It would mean a lot to me, no doubt about it,” he said.
Meanwhile, Maria Sharapova says it is “back to the drawing board” after she lost to Serena Williams for the 18th time in a row at the Australian Open.
Sharapova has not beaten Williams since 2004 and has now lost 19 of their 21 matches as the American strolled to a 6-4 6-1 win on Rod Laver Arena.
The Russian had opportunities, most notably with two break points at the end of the first set, but Williams delivered at the decisive moment and it was one-way traffic thereafter.
Three out of Sharapova’s last five major tournaments have now been ended at the hands of the world number one, who goes through in Melbourne to face Poland’s Agnieszka Radwanska in the semi-finals.
“It’s motivating because she’s at a different level. She makes you go back to the drawing board, not just for me, but for many other players. She makes you work. That’s inspiring,” said Sharapova.
