- Rafael Nadal admits he doubted he'd ever win another Grand Slam title after a three-year drought at the majors and an ongoing battle with injuries and poor form. On Sunday, the 31-year-old Spaniard coasted to a record 10th French Open title, demolishing Stan Wawrinka in a brutally one-sided final 6-2, 6-3, 6-1. "I have doubts every day but that's good as it makes me work hard with more intensity," he said. "You have to be humble and accept that you have to work to improve things. I have doubts today, I had doubts in the last three years, I will have doubts in a few days. Life is never clear. If you have no doubts, then you are very arrogant. I am not an arrogant person."
