Tennis legend Jim Courier has touched down in Melbourne ... pictured wearing their tennis outfits at Melbourne Park, and will also host a fashion event together next week.

Novak Djokovic has said he will avoid doing interviews on court at the Australian Open until he receives an apology from the Nine Network, after reporter Tony Jones's "mockery of Serbian fans".

Jim Courier doesn't expect to see Andy Murray in Novak Djokovic's box in the upcoming period but wouldn't be surprised at all if the Briton returned to the Serb's team for the French Open and Wimbledon.

A year after earning his first Grand Slam title at the same event, Sinner became the youngest man to leave Melbourne Park with the trophy two years in a row since Jim Courier in 1993.

Jannik Sinner won the Australian Open for the second consecutive year, defeating Alexander Zverev 6-3, 7-6 (4), 6-3.

So the beloved American’s absence at Melbourne Park this year was noticed almost immediately, as many took to social media to ask where Courier was during the early days of the tournament.

Jannik Sinner advances to his second straight Australian Open final by defeating Ben Shelton. The 23-year-old continues to break records, becoming the youngest to reach multiple finals since Jim Courier in the early 1990s.

Post-match interviews are the talk of Melbourne Park after Novak Djokovic snubbed Jim Courier. They are on people’s minds and Roger Rasheed would probably not want his chat with Ben Shelton ...

Sinner will try to add to his Australian Open trophy haul when he faces Alexander Zverev for the championship.

Defending champion Jannik Sinner continued his sizzling Australian Open run with a 7-6(2) 6-2 6-2 win over American 21st seed Ben Shelton to reach a second straight final at Melbourne Park and book a meeting with Alexander Zverev.

Sinner, 23, becomes the second-youngest man to win consecutive Australian Open singles titles, behind Jim Courier, who was 22. Additionally, Sinner is now the fifth man to win three consecutive hard-court Grand Slam singles titles in the Open Era.

It is now 53 years since Ken Rosewall defeated Mal Anderson to win the Australian Open at the age of 37. Should the No.7 seed, whose ball striking was breathtaking on Tuesday night, secure an 11th Australian Open title this week, that record will be his.
