While amassing a record haul of 20 Grand Slam titles, Federer has famously never handed a rival a walkover across 400 matches at Majors, and has never retired in over 1,500 tour-level matches. Serbia's Novak Djokovic pats Switzerland's Roger Federer after their match.
Federer had three break points to make it 5-1, but Djokovic dug deep to fend them off as he clawed back, breaking once more as the Swiss was serving for the set.
First, he beat Australia's John Millman in the third round after fighting back from being down, 8-4, in the final-set tiebreak to win his 100th Aussie Open match.
After the match, Federer admitted he was never confident about his chances of winning but was happy to have reached the semi-finals.

Novak is now set to face either Germany's Alexander Zverev or Austria's Dominic Thiam in the final of the Australian Open next.
