Juan Martin del Potro, a former Grand Slam champion, believes Jack Draper has the potential to rival Jannik Sinner and Carlos Alcaraz, but emphasizes the importance of Draper's physical well-being in achieving this goal. Draper, who has been tipped as a future Grand Slam contender, faces challenges in terms of consistency, fitness, and handling pressure on the biggest stages. Del Potro, who struggled with injuries throughout his career, including wrist and knee problems, understands the significance of physical resilience in tennis.

Despite his own experiences with injuries, Del Potro preferred competing against the likes of Roger Federer, Rafael Nadal, and Novak Djokovic, highlighting the need for a strong support team, including physical trainers and mental coaches, to overcome setbacks. Draper, who has battled anxiety and various injuries, including a recent knee issue, will aim to regain his form and compete at the highest level, with Del Potro expressing confidence in the future of British tennis.
