Rafael Nadal has denied he has ever used a banned substance to gain an edge or to speed up recovery from injury.

Nadal spoke out in the wake of Maria Sharapova’s failed drug test which has rocked the world of tennis.
The 14-time Grand Slam winner said former world No 1 Sharapova “should be punished” before using the opportunity to scotch unfounded allegations that he had used performance-enhancing drugs.

“I have never had the temptation of doing something wrong. I am very far from that, doping,” said the Spaniard, who has been hard hit in recent years by injury.
“I am a completely clean guy. I worked so hard during my career that when I get injured I never take nothing to be back quicker.”
The 29-year-old left-hander has been periodically dogged by whispers of doping during his trophy-laden career.

“I heard it a few times again about doping,” said Nadal. “I am a little bit tired with that.
“I believe in the sport and the values of the sport. The sport is an example for society. It is an example for the kids and if I am doing something that goes against that, I will be lying to myself, not lying to my opponents.”
Nadal said over the course of his career he has taken advantage of some new treatments for his knee problems, like stem-cell therapy and Platelet Rich Plasma (PRP) therapy, often known as blood spinning.

“I have been open all my career. I never tried to hide nothing that I did,” Nadal said. “I did PRP and then I did stem cells.
“The first time with PRP it worked fantastic and the second time it was bad. I had to stop playing tennis for seven months.
“And with stem cells I used it two times on my knees and it worked very well. “I am not doing, never did, and never going to do something wrong.”

Nadal added there is a Spanish team doctor who monitors what medication the players are taking to make sure it is safe.
“He has been the doctor for all the Spanish players for a number of years. I would never take nothing that he doesn’t know about,” he said.
