Alex de Minaur issued a brutal putdown to a Novak Djokovic superfan on social media following his one-sided loss to Jannik Sinner in the quarter-finals of the Australian Open.

Alex de Minaur has confirmed that he does not have the necessary weapons to put Jannik Sinner in trouble. The Australian ace has always been defeated by the Italian on the professional tour and the quarterfinal of the 2025 Australian Open was no exception.

Alex de Minaur admits he faces a "battle" to progress to the fourth round of the Australian Open on Saturday, despite Novak Djokovic predicting big things from the home favourite at Melbourne Park. De Minaur is yet to drop a set at his home slam but faces his sternest test yet in a third round clash against Argentina's World No.

Alex de Minaur is through to the quarterfinals of the Australian Open for the first time, defeating American giant-killer Alex Michelsen.

Sinner toppled de Minaur 6-3, 6-2, 6-1 in an hour and 48 minutes at Rod Laver Arena, shuttering the dreams of the home nation. De Minaur will have to find improvements to become a Major contender, having lost all five Australian Open matches versus the top-10 rivals!

De Minaur won five games in that fourth-round loss to Djokovic in 2023, and six in his quarter-final defeat to Sinner in this year’s quarter-final. Alex de Minaur claps back at an online troll and he has the full backing of the Grand Slam Daily team.

One envisages that when his head hit the pillow on Wednesday, he might instead have been reliving a tennis version of a Nightmare on Elm Street, with Jannik Sinner taking the role of Freddy Krueger. He knifed and diced “Demon” in a ruthless manner on Rod Laver Arena.

The 24-time slam champion, who is trying to win a record-extending 11th title at Melbourne Park, played less tennis than many of his rivals did in 2024 while failing to win a slam. Instead they were split between Jannik Sinner (Australian, US) and Carlos Alcaraz (French, Wimbledon).

Earlier in the day, Iga Swiatek cruised past Emma Navarro 6-1, 6-2 in their Women’s Singles quarter-final while Madison Keys secured a surprising 3-6, 6-3, 6-4 victory over Elina Svitolina to set up a meeting with Swiatek tomorrow.

Jannik Sinner destroyed the Demon to ensure Australia’s wait for a male winner in their own Grand Slam will hit 50 years of hurt. World No.212 Mark Edmonson, who worked as a window cleaner, was the last Aussie male champion way back in 1976.
