Action speaks louder than words.
Unless the words come from action man Rafael Nadal.
Watch: Year of the Murrays
Andy Murray reveals advice he received from a teenage Nadal after a racquetball game impacted his junior career.
In a new interview with Graham Bensinger, Murray says talking with the young Rafa convinced him he had to leave his native Scotland and move to Spain to pursue his dreams of a pro career.
"He didn't speak much English, I didn't speak much Spanish," Murray recalls of his initial meeting with Nadal. "But I just asked him about how he trains over in Spain and who he trains with. He was practicing for a few hours a day when he was there he was practicing with Carlos Moya, who is a former number one in the world and won the French Open. And I was practicing just a few hours a week with my brother.
"That was when I realized if I wanted to try to go to the next level and become a professional I was going to have to sort of change the environment I was training in. That's one of the reasons I moved to Spain."
Murray says the amount of training time a teenage Nadal committed made him realize he had to make a move to increase his own practice time realize his true potential.
"When you're very competitive, even at that age, that was when you start to realize I didn't have enough sort of opportunity in Scotland," Murray says. "I couldn't do it, the weather, not enough courts and obviously with school I couldn't play enough. He was by far the best player. He's one year older than me and he was a lot better than all the players there. One of the reasons for that was he was getting great practice with top players and enough hours on the court."
The world No. 1 also reveals he's so wary of drug tests, he limits supplemental intake to the essentials: Fish oil, glucosamine and the occasional protein shake.
"I've been working really, really hard to get into the position I'm in," Murray tells Bensinger. "I don't want to mess up by just taking a whole bunch of products not knowing what's in them and then failing a drug test."
"So you've got to be very, very careful as an athlete and very professional," Murray says. "I take basic stuff like fish oil, glucosamine for my joints and I'll take protein shakes from time to time."
