Tennis fans are expressing concern for Rafael Nadal's health after he shared a recent photo with Roger Federer, showcasing a noticeably slimmer physique. The image, posted on social media with the caption 'Look who I found in Madrid!', has sparked mixed reactions. While many fans praised the two tennis legends, others were shocked by Nadal's transformation from his previously muscular build, which helped him secure 22 Grand Slam titles, including 14 at the French Open. Comments on platforms like X and Instagram included remarks about Nadal appearing 'gaunt' and 'aged', with some fans worrying about potential long-term health effects from his retirement in November 2024. However, not all feedback was negative; some defended Nadal's appearance, emphasizing that such changes are typical for retired athletes, as noted by Yahoo Sports senior writer Dan Wolken. He pointed out that the body of a retired athlete will naturally differ from that of an active competitor, as they no longer engage in the rigorous training required at the professional level.
