Red Devil fighter Gegard Mousasi jettisoned his habitually laid-back demeanor and opened fire on former WEC champion Paulo Filho earlier this week, labeling him "a little donkey on steroids", covered here by The Garv.

Mousasi's venom-laced comments were a retort to Filho's instigative boasting on Tatame, and now Filho has sustained the verbal volley by responding to Mousasi's highly-inflammatory steroid accusation.  Originally posted on terra.com.br, Filho had the following to say in the interview:  (translation via MMABay)

“I didn’t take any steroid. How could I have taken steroids before losing 9 kilos?” “It’s his fault. He wants to talk, but the truth is he is afraid. He watched me in the past and I also watched him. He didn’t change his game too much. He’s the same: paper-thin and just put on some weight.” “And it’s clear he doesn’t respect the opponent because he always has this ‘superior’ look on his face. He’s in good momentum right now but the Brazilian light-heavyweights are able to beat him up - and I’m one of them.” “The fight isn’t signed yet but it will happen. DREAM and Strikeforce have connection. Wherever he wants to face me off, we’ll fight. Be sure we will put on this challenge.” “Depending on the position I will punish him on the ground. All fights end up clinched and he falls easily. I’ll use my jiu-jitsu base to annul his game.”
