Jannik Sinner has made two huge changes to his team ahead of his Wimbledon 2025 campaign. The Italian will be the top seed at the event as he will look to win the coveted grass major for the first time.While the tennis world was focused on the unveiling of the 2025 Wimbledon championship gentlemen's singles draw, another big news was made around the same time regarding ATP's World No. 1. Sky Sports reported that Sinner's trainer, Marco Panichi, and physiotherapist, Ulises Badio, were no longer a part of the Italian's team.While it is yet to be revealed who will replace Marco Panichi and Ulises Badio, Jannik Sinner is currently joined by osteopath Andrea Cipolla at Wimbledon, alongside his coaches Darren Cahill and Simone Vagnozzi.Panichi and Badio joined the World No. 1's team in September last year, replacing his previous trainer, Umberto Ferrara, and physiotherapist, Giacomo Naldi, after the big Clostebol doping ordeal, which ended this year with the Italian receiving a three-month suspension.Sinner tested positive for the banned substance Clostebol back during the Indian Wells Masters last year; however, he argued the substance entered his body via bare-handed body massages from his now ex-pysiotherapist Naldi, who was using a healing spray, containing Clostebol, to heal a wound on his finger. He split with them in August last year.Interestingly, this will also be Sinner's final year with his long-time coach Darren Cahill."I feel very, very lucky and happy to be his last player on Tour" - Jannik Sinner gets emotional speaking about Darren Cahill's retirement in 2026Jannik Sinner and Darren Cahill at the 2024 Australian Open - Source: GettyJannik Sinner's coach Darren Cahill has been on the Tour for a long time and has also coached the likes of Andre Agassi, Lleyton Hewitt, and Simona Halep. He joined the Italian's team in 2022 and helped him become the player he is today. However, he has made the decision to retire following the 2025 season.Speaking about news during a press conference at the Australian Open this year, Jannik Sinner got emotional speaking about the news and felt lucky to be the final player to be coached by Cahill.“He brought me so many things,” said Sinner. "One year is still long. I don't want to talk so much about his retirement. I feel very, very lucky and happy to be his last player on Tour. He has been an amazing, amazing coach and person, not only for me but for all the other players he has worked with.”Continuing his thoughts, he also hoped to enjoy a nice final season with Cahill. The Italian has already won the Australian Open and made it to the final of the Italian Open and the French Open, but suffered heartbreak to Carlos Alcaraz on both occasions.“For me it's just a huge honour. Hopefully we can make a nice season. But let's see what's coming in the future. He has a beautiful family, so many great things to come for him also after his tennis job. Let's see. But the year is still long.”Up next, Jannik Sinner will look to move on from his French Open final heartbreak as he looks to win his first Wimbledon title. The top seed will kick his campaign off against Luca Nardi.
