Juan Martin del Potro, a former Grand Slam winner, believes Jack Draper has the potential to compete with top players like Jannik Sinner and Carlos Alcaraz, but notes that Draper needs to build confidence in his body to perform at his best. Del Potro, who struggled with injuries throughout his career, including wrist and knee problems, emphasized the importance of consistency, fitness, and managing expectations for Draper's success. The British star has shown promise, defeating Novak Djokovic and making a strong run in the Indian Wells title defense, but has also faced setbacks due to injuries, including a bone stress injury in his left arm and a recent knee issue.
Del Potro advised Draper to focus on building a strong support team, including a physical trainer, physio, and mental coach, to help him navigate the challenges of professional tennis. With the Madrid Open approaching, Draper will look to regain his form and make a strong showing, while Del Potro will be watching from the sidelines, having retired in 2022 due to ongoing injury issues.
