WATCH: Birthday boy Rafael Nadal's Paris interview on Tennis Channel

When Rafael Nadal first played at the French Open in 2005, he was a highly touted prospect. Twelve years later, on his 31st birthday, the Spaniard is an all-time great—as well a great interview.

The 14-time Grand Slam champion, whose history at this tournament surpasses all others, spoke with Tennis Channel's Martina Navratilova and Brett Haber on Saturday in a wide-ranging interview that covers, among other topics:

—The specifics of what happened during last year's French Open, when he was forced to withdraw due to injury

—Whether or not he sees himself as the "favorite" at this year's tournament

—His passion for the sport and its future, as it relates to his new tennis academy in his hometown of Mallorca

Nadal also received a birthday cake and present, as one does.
