Juan Manuel Marquez (53-5-1, 39KOs) has issued a response to the recent comments that were made by strength and conditioning coach Alex Ariza, and other members of Manny Pacquiao's team, regarding the controversial past of Marquez's conditioning coach Angel Hernandez, who years ago was heavly involved in the BALCO Lab steroid scandal and during legal hearings he disclosed his involvement in distributing banned substances to Olympic athletes. Marquez faces Pacquiao (53-3-2, 38KOs) for the WBO welterweight title on November 12th at the MGM Grand in Las Vegas.

"I'd be delighted to take a test. I've never taken banned substances. My physical condition is thanks to the hard work that I've put in. In my 18 years as a pro boxer, I've never trained like this, with three daily sessions - running, weights and training very hard in the gym. I don't care what Pacquiao's team has to say. My mind is focused on making an intelligent fight and to secure the knockout," Marquez said.
