Manny Pacquiao's trainer Freddie Roach insists the boxer will punish Brandon Rios for a gym bust-up on Wednesday.
Pacquiao, an eight-weight world champion, will meet American Rios in Macau on Saturday, yet their bout has been overshadowed by a fiery pre-fight altercation.

The incident saw Roach clash with Rios' trainer Robert Garcia and conditioning coach Alex Ariza, with the latter kicking Roach in the chest and allegedly mocking his having Parkinson's disease.
Pacquiao was the calmest of the pair in their subsequent press conference and has assured Roach that Rios will pay for his team's conduct in the ring.
"Pacquiao said to me, 'Are those the guys that made fun of you?' And I said yes, and he said, 'That's all I need to know,' and he walked away," Roach said.
"He told me he's going to take care of this guy quickly."
Both boxers come into the clash following losses in their previous fights, with Pacquiao aiming to put 2012 defeats to Timothy Bradley and Juan Manuel Marquez behind him.
