Former champion Amir Khan was pretty open about his reasons for firing trainer Freddie Roach. When the British star was interviewed a few weeks ago, he said the main reason for making a change was the high volume of fighters that Roach was working with. Khan said grew tired of sharing training camps with Manny Pacquiao and other boxers who are working Roach.

Khan then hired Virgil Hunter, who himself is starting to build a big roster of boxers at his gym in California.

Another reason for splitting with Roach, according to Khan, is the trainer's day to day battle with Parkinson's disease. Khan believes Roach's condition is getting worse and the disease is starting to affect his routines as a trainer.

"Freddie's illness, it's very hard to see him as he's getting older. I believe that he's getting worse, and I wish him all the best. Freddie is still, with the Parkinson's disease, doing a great job working the mitts and working with fighters day in, day out. I just believe that I need someone who is going to work me that bit harder and get the best out of me," Khan said.

Khan returns on December 15th in a Showtime televised fight against Carlos Molina.
