Jannik Sinner’s 2025 season began with his second triumph at the Australian Open, which certified his superiority over all opponents on hard courts. The world number 1 has been practically unstoppable in the last twelve months, having expressed an impressive level without any drop despite the strong stress resulting from the doping case that concerned him.
The numbers of the Italian ace from January 2024 until today are truly mind-blowing and the gap he has created over all his rivals in the ATP ranking is truly frightening. Despite becoming the youngest ever to win Roland Garros and Wimbledon in the same year, his great rival Carlos Alcaraz is almost 5000 points away from him.
After his sensational triumph at Melbourne Park, the 23-year-old from Sesto Pusteria decided not to defend his title in Rotterdam and to recharge his batteries. The 3-time Grand Slam champion will play only one tournament in February, the Doha ATP 500, before focusing on the Masters 1000 in Indian Wells and Miami.
Seppi could replace Cahill
Behind Sinner’s rise, there is certainly the valuable contribution of his entire team. Simone Vagnozzi and Darren Cahill have done an outstanding job both on and off the court, helping Jannik overcome the difficulties related to the doping case in recent months.
During the 2025 AO, the world No.1 revealed that 2025 will be the last year Cahill will be by his side. The legendary Australian coach wants to devote himself totally to his family from 2026 and has made the decision to quit after leading the Italian to the first position in the ATP ranking.
Vagnozzi has already explained that he will not be able to follow Jannik for the whole year, which is why it will be necessary to enter a new coach in the team.
According to reports from ‘La Gazzetta dello Sport’, one of the most suggestive names to replace Cahill is that of Andreas Seppi.
“I am honored that my name has been mentioned” – said the former world number 18. “I would like to emphasize that I have not yet been contacted by anyone, but if there was this possibility I would be truly honored to coach a champion like Sinner” – he added.
