Novak Djokovic’s relentless march towards a record 25th Grand Slam title gathered pace on Sunday as he outclassed 20th seed Adrian Mannarino to reach the quarter-finals of the Australian Open (AO). The Serbian ran rings around his French opponent on Rod Laver Arena, winning 6-0, 6-0, 6-3 and underlining his status as red-hot favourite to lift an 11th title at Melbourne Park. “I really wanted to lose that game in the third set because the tension was building up so much in the stadium,” he joked, referring to the possibility of winning without losing a game.
