Strength and conditioning coach Justin Fortune expects a brutal knockout if Amir Khan (31-3, 19KOs) steps in the ring with Manny Pacquiao (57-6-2, 38KOs).

Pacquiao-Khan is being discussed for a possible fight in early 2016.

Fortune worked with both fighters when they were stablemates at the Wild Card Boxing Club in Hollywood, California. During that period, Khan and Pacquiao were being trained by Freddie Roach and often sparred with each other during joint training camps.

Khan left Roach in 2012 and hired Virgil Hunter. Pacquiao still works very closely with Fortune and Roach.

In the opinion of Fortune, he feels Khan was a much better fighter when he was being trained by Roach. Khan has won five in a row since suffering back to back defeats to Danny Garcia and Lamont Peterson.

"Listen, when Khan was in London with his people in London, he was good. When he went with Freddie he was much, much better. Now he's up north with Virgil Hunter. Personally I think he's a wuss. I think Manny f***king knocks Khan out. Khan is fast and he's strong but he can box his ass off too, but so can Manny. He was better when he was with Freddie, way better," Fortune told ES News.
