Roger Federer has further cemented himself as one of the greatest athletes in history, winning a record 20th Grand Slam tennis title.

The 36-year-old defeated Croatian Marin Cilic in a see-sawing five-set match, 6-2 6-7 (7-5) 6-3 3-6 6-1, to claim his sixth Australian Open, joining Novak Djokovic and Roy Emerson as the only other men to do so.

The Swiss maestro broke down in tears as he raised the Norman Brookes Challenge Cup, thanking his family, his support team and fans around the world.

“I’m so happy. It’s unbelievable.

“The fairytale continues for us, for me. After the great year I had last year, it’s incredible.”

Federer is closing in on Rafael Nadal’s world-number-one ranking as well as Serena Williams’ open-era record of 23 Grand Slam singles titles.

Alan Jones speaks with Aussie tennis legend Lleyton Hewitt for a full wrap of the match and the tournament.

The Channel 7 commentator says Federer is looking as good as ever.

“It’s incredible you know, we’re the same age.

“The way he’s gone about it for so long now. He’s moving as well as ever and that was an epic final.”
