Aussie Open 2019: Novak Djokovic defeats Jo-Wilfried Tsonga to reach third round

World number one Novak Djokovic reached the Australian Open third round with a straight-set victory over Jo-Wilfried Tsonga.

The six-time champion in Melbourne defeat the 33-year-old Frenchman 6-3 7-5 6-4.

After a knee injury restricted him to 12 matches in 2018, Tsonga, whose ranking has fallen to 177, showed flashes of his ability but the 31-year-old Serb was always in control.

Djokovic will face 19-year-old Canadian Denis Shapovalov, the 25th seed, next.

The match against Tsonga brought back the memories of 2008 final in Melbourne, which the Serb won in four sets to secure his first Grand Slam title.

"You could feel the tension on court at the beginning. We felt a lot of emotion and tried to play a great game," said Djokovic.

"It's always tough to play Jo. He has struggled with injury and his ranking doesn't do him justice in my eyes."
