Pacquiao is just a shell of what he was five years ago, says former conditioning coach Alex Ariza

Manny Pacquiao's former strength and conditioning coach Alex Ariza is convinced that the Filipino ring icon is no longer the same athlete he trained years ago.

The controversial Ariza who kicked Freddie Roach in a training session with Brandon Rios in 2013, will get another chance to beat his old boss after signing as Floyd Mayweather's new conditioning coach months ago.

"You know, if you talk to the trainers and fighters who know this sport, there's a reason why they're all picking Floyd to win," Ariza told fighthype.com.

"For me, the guy that I trained five years ago, the guy that was walking through walls and that was literally breaking bones with shots and comatizing people with single shots, the opponent that we have now is a shell of that guy."

As for the upcoming showdown between Pacquiao and Mayweather on May 2, Ariza feels rather confident of his new boss' chances come fight night.

"For me, I think I've been in harder fights," says Ariza.

"It's just very hard for me to see where our weaknesses are in this fight versus our opponent's weaknesses." - RAF, GMA News
