Juan Martin del Potro, a former Grand Slam winner, believes Jack Draper has the potential to rival top players like Jannik Sinner and Carlos Alcaraz, but notes that Draper must first build confidence in his body. Draper, who has been tipped as a future Grand Slam contender, faces challenges in maintaining consistency, fitness, and managing expectations on the biggest stages.

Del Potro, who struggled with injuries throughout his career, including wrist and knee problems, advises Draper to focus on building a strong support team to help him overcome setbacks. Draper recently returned to competition after a six-month absence due to a bone stress injury in his left arm and has shown promising results, including a win over Novak Djokovic.

However, he has also battled anxiety issues and injuries to his hip, knee, and arm. Del Potro, who lost to Andy Murray in the Olympic men's singles final in 2016, emphasizes the importance of mental and physical resilience in overcoming injuries and achieving success in tennis. With the Madrid Open approaching, Draper will look to regain his form and compete against the world's top players.
