LOS ANGELES --- Chris Arreola had nothing but respect for Bermane Stiverne after being knocked out in the sixth round on Saturday night at USC's Galen center on ESPN.

Stiverne floored Arreola with a right hand for the first knockdown in the sixth round and it proved to be the beginning of the end. He got knocked down one more time and barely beat the count before a follow-up flurry forced the referee to stop the fight.

"The power is his hand speed," Arreola said. "That's the main power. I didn't see that punch coming at all ... at all. But for reals I didn't see that punch coming. That's his power. It's so fast that when he connects it's like a bulldozer. It hurts. It didn't hurt me, but, 'Oh sh--, I'm on the ground.' So that's what he has. His main power is his speed. It's blinding. You don't really see it. I didn't see that right hand coming."

How does Arreola feel Stiverne would do against Deontay Wilder, the WBC's mandatory challenger at heavyweight, or Wladimir Klitschko, the WBO/IBO/WBA/IBF heavyweight champion?

"Wilder, to me, hasn't proved himeself," Arreola said. "So Bermane would easily take him out. Klitschko? I wouldn't know. I haven't fought him, but I guarantee you he would give him a run for his money. He ain't know (Alex) Leapai. That's for sure."
