Juan Martin del Potro, a former Grand Slam winner, believes Jack Draper has the potential to challenge top players like Jannik Sinner and Carlos Alcaraz, but notes that Draper must first build confidence in his physical ability to withstand the demands of professional tennis. Del Potro, who has struggled with injuries throughout his career, including wrist and knee problems, emphasized the importance of consistency, fitness, and mental toughness for success at the highest level.

Draper, who has been dealing with his own set of injuries, including a recent bone stress injury in his left arm, is set to compete in the Mutua Madrid Open. Del Potro shared his own experiences with injuries, stating that they were the most challenging aspect of his career, but also highlighted the need for a strong support team, including physical trainers, physiotherapists, and mental coaches, to overcome these challenges.

The Madrid Open, which will feature top players like Draper, Cam Norrie, and Emma Raducanu, will be broadcast live on Sky Sports Tennis, with the main draw action starting on April 21.
