The 14-time Grand Slam champion said he will sue a former French secretary of sport, who charged him with doping violations.

Roselyne Bachelot, former French secretary of sport, told the French TV program Le Grand 8 that  Nadal's break from tennis in 2012 was "without any doubt because he tested positive (for a banned substance)" rather than due to injury.

An incensed Nadal said he will sue Bachelot.

"I have been working so much since I have five years old, all my career, to have the success that I had, and always with the right way, always practicing with passion, with intensity, with love for the game," Nadal told the media after his Indian Wells win over Gilles Muller. "There is a couple of times I heard comments like this, and that's what —this gonna be the last one, because I gonna sue her. I am tired about these things."

Nadal also vowed to take legal action against "everyone" who makes unfounded doping accusations against him in the future.

"I let it go a few times in the past. Not more, you know. I know how tough I worked to be here," Nadal said. "To listen, to heard those comments from a person that should be serious, because was minister of a big country and a great country like France. So I gonna sue her, and I gonna sue everyone who gonna comment something similar in the future, because I am tired of that."

Asked why he believes he has been the subject of several doping rumors and allegations in the past, Nadal said he doesn't know and doesn't care. But vowed he will not tolerate it anymore and will sue anyone who makes unfounded doping allegations against him.

"I don't care. I really don't care because I know how I arrived to where I am," Nadal told the media. "The people who know me knows very well how I arrived where I am. So, you know what? The past I didn't want to go for just this, to sue the people who said these things, because I didn't thought that they were serious.

"But a minister of France should be serious. This time is the time to go against her. We gonna sue her, and since the day after day I tell you that everyone who has another comment in this way gonna happen the same, because that's too much for me."
