Jannik Sinner, Matteo Berrettini strongly denies a'hypothesis.

It has been several days but the tennis world continues to question the sudden collapse that cost Jannik Sinner Roland Garros. Among the disparate opinions after the loss to Juan Manuel Cerundolo is that of a mental problem: even Boris Becker suggested it.
A hypothesis that does not agree at all with Matteo Berrettini, who at a press conference in Paris said he was skeptical that the world number one has problems on the psychological level. “Jannik has proven a million times over that he is a champion who is making tennis history, not just Italian tennis; he has done things that not even others we know well have been able to do.”
“I don’t think he has blocked because of the fear of being sick. It’s always said that if you’re afraid of something then you carry it with you, but it’s hard to judge and I don’t think it can be a general rule for everyone.” Berrettini gave the example of himself: the physical problems of recent years have worn him down mentally as well. “I’m not like him: I know that when I’m afraid to go over a pain or discomfort, over an injury, it’s really hard because everything collapses on you. I’ve been working on that as well, to accept that the fear comes but to have weapons so that this thing doesn’t become so big to handle.”
The world number one is following a specific schedule ahead of Wimbledon, starting June 29, a tournament he will defend as defending champion. Among the planned steps, there is talk of a visit to the JMedical in Turin to carry out a complete 360-degree check-up, with the aim of understanding how to prevent a similar situation to the one experienced against Cerundolo from happening again. Rest, analyze what happened with lucidity and find the necessary countermeasures: this is the plan of the South Tyrolean to make himself 100% on the lawns of the All England Club.
