Rafael Nadal put his remarkable resurgence down to his "love for the game" after claiming a 16th Grand Slam title at the US Open.
The 31-year-old Spaniard beat South Africa's Kevin Anderson 6-3 6-3 6-4 to win his third title in New York.
Following his French Open success in June, it is the first time since 2013 that Nadal has won two Slams in a year.
"I wake up every morning with the passion to go on court and to try to improve things," he said.
"I still want to compete and still feel the nerves every time that I go on court.
