The World lightweight champion, Juan Manuel Marquez, has defended his stand his new strength and conditioning coach, Angel Hernandez, after reports revealing shady past of Hernandez came out.

Hernandez admitted to a San Francisco court in May 2008 that he had supplied Olympians, including Marion Jones and Tim Montgomery. Marquez said he has no knowledge of his new nutritionist’s dealings with anabolic steroids.

“If they want to do whatever doping or drug testing they want to do, Olympic-style, or whatever they want to do, I’ll do it. I’m prepared,” Marquez said.
