Djokovic through to Federer semi at Aussie Open
Five-time winner Novak Djokovic downed Japan's Kei Nishikori on Tuesday to set up a much-anticipated Australian Open semi-final with Roger Federer.
The world number one overcame an off-key Nishikori 6-3, 6-2, 6-4 in two hours, seven minutes on Rod Laver Arena to reach the last four.
Djokovic will now face 17-time Grand Slam champion Federer in their 45th meeting with each player winning 22 times so far.
It will be 10-time major-winner Djokovic's 29th Grand Slam semi-final and sixth in Melbourne.
"It's always a great challenge to play Roger," Djokovic said of Thursday's semi-final. "You don't need to spend any words on his achievements, what he's done for the sport.
"He's a great champion, I have a lot of respect for him and we're going to have a good match."
Djokovic, with his win over Nishikori, is on a 19-match Grand Slam winning streak and has not lost at a major tournament since he was defeated by Stan Wawrinka in last year's French Open final.
The Serb's longest Grand Slam streak stands at 27, which took in the titles at 2011 Wimbledon, the 2011 US Open and the 2012 Australian Open, and a runner-up finish at 2012 Roland Garros.
