"Ross better worry about my hands," Guillard said. "I am the hardest hitting '55er at 155. I've watched him bang with guys, I've watched him connect on good shots and not even drop people. Everybody I hit, I drop. Everybody I hit, I f--k them up.
"Him being a harder hitter than me, I don't think that's going to be possible."
Guillard says he wants to finish the fight and not let it go to a decision.
"I don't like fights going to decisions, especially in other people's hometowns, so I'm looking to finish this fight," Guillard said. "This is going to be a fight where I'm not only fighting him, but against the clock because I don't want any bad decisions, I don't want any close decisions. I want to finish the fight and know that I won the fight.
"I've got to go in there and do my job. I'm not coming all the way to England to get my ass whipped. I don't want to have to fly all the way back home depressed."
Guillard explained that he's in a good place and he's ready to handle business in England.
"All my coaches, they had their credentials, but sometimes it's also a business, and to me my family comes before anybody else," Guillard explained. "I have to be there for my family and unfortunately, certain things didn't work out with certain guys, and you have to move on.
"I know everything worked out perfect with where I'm at at American Top Team. I got new management, I got a new team, I got a new mouth guard, I got new everything. I got rid of all the old stuff, and out with the old, in with the new."
Guillard knows that your job is never truly safe in the UFC unless you're a champion. With that said, he's looking to put on a crisp performance against Pearson to ensure he's a true contender.
"With the UFC, you can win one and lose one and still be cut," Guillard said. "So right now I'm still fighting for my job. I'm fighting for my job until I feel I have a belt around my waist to secure my job. That's the only time you have job security is with the belt around your waist."
Guillard fights Pearson on Saturday at UFC Fight Night 30 in England.
