Isner warns Alcaraz: "If he doesn't perform in Australia, a lot of people will blame him for going to the US instead of preparing as well as he could."
Retired from the courts since the US Open 2023, John Isner still keeps a close eye on tennis news.
On the Nothing Major podcast, the former world No. 8 and winner of the 2018 Miami Masters 1000 was keen to send a message to Carlos Alcaraz.
The words are very similar to what Andy Roddick has been saying in recent days about the Spaniard's schedule.
"Nobody has anything against Carlos deciding to play these exhibitions in the United States in December to cash two huge checks.
But Sinner took a different line, and kept his head down. Jannik wasted no time in getting back to work, keeping a low profile to return to the court in top form.
Both will be ready for the Australian Open. But I think that if Carlos doesn't perform as well as he hopes in Australia, a lot of people will blame him for having gone to the United States to have fun instead of preparing as well as possible like his rival.
I don't think that's fair, because anyone can choose to prepare as they see fit. But if it does happen, I think it will happen that way," he elaborated.
