The confirmation comes after former world number two Alex Corretja claimed that the Serbian is “stronger than ever”. That is despite the 34-year-old missing out on several important tournaments over his decision to avoid the Covid vaccine.
“I think that today, with everything that has happened to him in recent years, since the US Open 2020, the final he lost last year, this year in Australia, he is stronger than ever,” the Spaniard said.
“I admire him deeply, because he says what he feels. He’s not saying the right things to make people love him. You can agree with his way of thinking to a lesser or higher degree, but you cannot criticize him for being consistent in his principles.”
