Lance Armstrong insists he is not bothered by being "particularly monitored" by anti-doping controls at Tour de France.

 French sports minister Roselyne Bachelot said today an especially close eye would be kept on the Astana rider.

"The (doping) controls will be multiplied, and I tell Lance Armstrong that he will be particularly, particularly, particularly monitored," Bachelot told TV channel i-Tele.

"There needs to be a really very, very active fight against doping. The organisers know how much a positive doping test could have harmful effects."

The seven-time Tour winner is, though, unconcerned, claiming he is used to being under the spotlight.

"No worries, it's been this way for 10 years. I have nothing to hide," Armstrong said on his Twitter page.

The race starts tomorrow in Monaco.
