Former ATP player Kristof Vliegen discusses the challenges Novak Djokovic faces in winning the French Open, highlighting the physical demands of the tournament. While he acknowledges Djokovic's potential at Wimbledon, Vliegen believes the French Open's intense physicality makes it a significant hurdle for the Serb star. Vliegen explains that Djokovic would need to defeat both Carlos Alcaraz and Jannik Sinner within 48 hours, which is a formidable task given the demanding nature of the tournament. Despite this, Vliegen leaves open the possibility of Djokovic's success at Wimbledon, suggesting he may perform better there compared to the French Open.
