This is the story of two players who have marked the history of world tennis so much that some end up confusing them. On Twitter, Roger Federer recounted an episode that happened to him during the Formula 1 Grand Prix in Miami on May 7. “A guy asked me, ‘Can I have a picture with you, Mr. Nadal?’ I replied that I was not Mr. Nadal. He apologized and left without taking a photo. Roger Federer (retired since September) and Rafael Nadal (still suffering from left hip pain) are not on the starting line at Roland-Garros (May 28-June 11).
