World number one Novak Djokovic has set up a blockbuster Australian Open semifinal showdown with Roger Federer after beating number seven seed Kei Nishikori in straight sets on Tuesday.
The top seeded Serbian defeated the seventh seed Japanese 6-3, 6-2, 6-4 in the quarterfinal clash that lasted more than two hours.
The defending champion will face the world number three for the 45th time for a place in the final, with the current head-to-head record standing at 22 wins apiece.
This will be their third successive showdowns at the majors after meeting in both the 2015 Wimbledon and US Open finals.
