Former Serbian tennis star Viktor Troicki says the Australian Open crowd booing an injured Novak Djokovic was a plain disrespectful and disappointing move. Moments after Alexander Zverev won the first set 7-6 (5) which lasted an hour and 21 minutes, the record 10-time Australian Open winner walked to the net and retired.

Serbian Davis Cup captain Viktor Troicki has demanded Channel Nine commentator Tony Jones be banned from covering tennis for life following controversial comments about Novak Djokovic at the Australian Open.

And just as Djokovic had a couple of hurdles by the names of Roger Federer and Rafael Nadal to deal with, Sinner is not alone among the newest generation of tennis stars. His top rival at this point is Carlos Alcaraz, who has four Slam victories at age 21 — and won all three matches he played against Sinner in 2024.
