The unsettling distance between Cahill and Sinner: "Surgery should be an option"

Jannik Sinner will be out of competition for almost half a year, and that situation is not easy to manage for any elite athlete. Doubts about how to treat the injury may start to arise, attitudes toward close people can be sensitive to change, and that is what may be happening between the Italian and Darren Cahill, one of his coaches.

This was stated by Brad Gilbert on the Big T podcast. The great relationship that the American coach maintains with Darren Cahill led to him being asked about the role of the Australian during this difficult phase for Jannik Sinner. The one who shaped the careers of legends like Agassi, Roddick, Murray, or Gauff offered a really striking perspective that generates uncertainty among the Italian player’s fans.

"I've been talking a lot with Darren lately. He told me that it all started when he was on his way to Los Angeles airport to fly to Cincinnati. He was supposed to meet with Jannik there, but received a last-minute call informing him that the Italian would not be competing after all. Since that moment, he has been waiting for updates, and that is very frustrating," he commented.

These words reveal a clear distancing and isolation of Darren Cahill from the core of his team, along with Simone Vagnozzi and all the medical staff that, in different clinics, is trying to heal the player's battered knee. Even more unsettling is Gilbert's assessment of how Jannik's injury is behaving.

"What they tell me is that Jannik is following the doctors' advice, who want to avoid surgery. They ask him to take a few days off and then return to training. But the pain comes back. Some days he feels fine, but in the end, he feels discomfort. There are many doctors involved in the case, up to three different ones," he explained.

Gilbert believes surgery should be considered if the problems persist

At this point, the big question hovering over the minds of Brad Gilbert and, possibly, Darren Cahill and the entire tennis world is what happens if rest is not enough for the knee to recover. This is articulated by the American, who seems to take on the role of an informal spokesperson for Cahill, whose distancing from Sinner may be due to different views on how to approach the injury treatment.

"Can you imagine if we reach December, when he has to intensify his training to get ready for the Australian Open, and the pain persists? That scenario would make surgery have to be an option. Surgery is always something to be avoided, but the truth is that right now, a knee operation is much less invasive than it was 30 years ago," asserted a Brad Gilbert who opens up many debates and sows the seed of a significant rift between Darren Cahill and Jannik Sinner.
