Freddie Roach says preparing for the fight is the biggest challenge of his life




"It's the biggest challenge of my career, by far," the American said in Macau, where he is preparing China's Zou Shiming to challenge Thailand's Amnat Ruenroeng for the IBF flyweight championship at Cotai Arena on Saturday.
"Floyd's undefeated. He's talented, He's unique. Here's a guy I first saw when he was five years old in the gym. And he was a good fighter then," Roach said.
