Jannik Sinner’s rise to the top of the tennis world has been nothing short of meteoric. The young Italian has captured the hearts of fans with his powerful game, unwavering focus, and humble demeanor. While Sinner’s talent and dedication are undeniable, a crucial piece of the puzzle in his development has been the guidance he’s received from his coaching team. Recently, details have emerged about a pivotal piece of advice from none other than Novak Djokovic, which played a significant role in shaping Sinner’s game.
The Coaching Team Behind Sinner’s Success
Before delving into Djokovic’s advice, it’s essential to acknowledge the team that has guided Sinner throughout his journey. Currently, Sinner is co-coached by Simone Vagnozzi and Darren Cahill. Vagnozzi, a former Italian tennis player, has been working with Sinner since February 2022. Cahill, a highly respected coach with a proven track record, joined the team in June 2022. Cahill has previously coached several high-profile players, including Andre Agassi, Lleyton Hewitt, Simona Halep. The duo jointly won the “Coach of the Year” award at the 2023 ATP Awards for their work with Sinner.
Previously, Riccardo Piatti was Sinner’s first coach, guiding him from the age of 13. Piatti, who had also worked with Novak Djokovic, played a crucial role in Sinner’s formative years. Other members of Sinner’s support team include physiotherapist Giacomo Naldi (joined in February 2023) and fitness coach Umberto Ferrara (since June 2022), who ensures Sinner remains in peak physical condition. The Italian also switched his management to AVIMA Sports & Business Management in 2025, led by Alex Vittur.
Wimbledon 2022: A Turning Point
The story of Djokovic’s advice dates back to the 2022 Wimbledon Championships. Sinner and Djokovic faced off in the quarterfinals, where Djokovic ultimately prevailed in five sets after Sinner had taken a two-set lead. Despite the loss, the match proved to be a valuable learning experience for Sinner and his team.
Following the match, Darren Cahill, who had recently started working with Sinner, seized the opportunity to seek advice from Djokovic, one of the sport’s all-time greats. What followed was a candid and insightful assessment of Sinner’s game that would have a lasting impact.
Djokovic’s Unvarnished Assessment
According to Cahill, when he asked Djokovic for his thoughts on Sinner’s game, the Serbian responded with remarkable honesty. Djokovic pointed out that while Sinner possessed impressive ball-striking abilities, his game lacked variation.
Djokovic’s specific observations included:
- Lack of Shot Variation: Sinner tended to hit the ball in a similar manner, without employing enough variety in terms of spin, pace, and trajectory.
- Limited Net Play: Sinner rarely ventured to the net, missing opportunities to shorten points and put pressure on his opponents.
- Predictable Returns: Sinner’s return game lacked aggression and variety, making it easier for opponents to serve effectively.
Cahill noted that while he and his team were already aware of these areas for improvement, hearing it directly from Djokovic, a 24-time Grand Slam champion, carried significant weight and provided Sinner with a fresh perspective.
Implementing the Advice
Armed with Djokovic’s insights, Sinner and his team set about addressing the identified weaknesses in his game. This involved:
- Developing Shot Variation: Sinner worked on adding more spin to his shots, varying his pace, and utilizing different angles to disrupt his opponents’ rhythm.
- Incorporating Net Play: Sinner began practicing his volleys and approaches to the net, becoming more comfortable finishing points closer to the net.
- Aggressive Returns: Sinner focused on taking the initiative on his returns, stepping into the court and putting pressure on his opponents’ serves.
The Results Speak for Themselves
The changes implemented in Sinner’s game following Djokovic’s advice have yielded remarkable results. Sinner’s improved shot variation has made him a more unpredictable and versatile player, capable of adapting to different opponents and court surfaces. His willingness to come to the net has added a new dimension to his game, allowing him to shorten points and dictate play. Furthermore, his more aggressive return game has enabled him to put pressure on his opponents’ serves and create more opportunities to break.
Sinner’s progress has been evident in his improved results on the court. He has captured multiple titles, including the 2024 Australian Open and the 2024 US Open, and has risen to the top of the ATP rankings. He also won a Masters 1000 title in Toronto and reached seven finals in 2023. Sinner has also demonstrated his ability to compete with and defeat the top players in the world, including Djokovic himself, with Sinner now leading 5-4 in their head-to-head record.
Djokovic’s Perspective
Djokovic has also publicly acknowledged Sinner’s growth and development. Following a recent match, Djokovic praised Sinner’s physicality, fitness, and ball-striking abilities, noting that Sinner consistently plays at a high pace and is rarely off-balance.
A Lasting Impact
Novak Djokovic’s willingness to provide candid advice to Jannik Sinner and his coach Darren Cahill has had a profound impact on the young Italian’s career. By identifying key areas for improvement and offering specific suggestions, Djokovic helped Sinner unlock his full potential and transform into a Grand Slam champion and world number one. This story serves as a testament to the importance of mentorship, the value of honest feedback, and the transformative power of embracing change. As Sinner continues his journey, the lessons learned from Djokovic will undoubtedly continue to guide him toward even greater heights.
While Sinner is splitting with coach Darren Cahill at the end of 2025, with rumors that Carlos Moya is set to join Sinner’s coaching team in 2026, the foundation built with Cahill, with the crucial advice from Djokovic, will undoubtedly remain a cornerstone of Sinner’s continued success.
