Liam Williams hasn’t just studied Demetrius Andrade’s boxing style in preparation for their fight Saturday night in Hollywood, Florida.

The mandatory challenger for Andrade’s WBO middleweight title has observed Andrade outside of the ring as well. After listening to a lot of what Andrade has said about their fight and a lot of other topics, Williams isn’t impressed.

“He’s a clown,” Williams said. “I don’t think he’s wired right. He’s got a screw loose. His mannerisms, the way he acts and talks in his interviews, he’s just a little bit strange, and I can’t put my finger on it. He’s an oddball.”

Whatever Williams thinks about Andrade’s personality, the 28-year-old contender will encounter an undefeated two-division champion who is listed as a 4-1 favorite to beat him. Wales’ Williams (23-2-1, 18 KOs) is convinced, however, that he wants to win this fight more than the 6-feet-1 southpaw.

“I don’t think he has the same intensity as me,” Williams said. “I wear my heart on my sleeve. I can punch harder than him. I have a better engine than him. I’m going to bring it all on the night and I don’t think he has the answers.”

The 33-year-old Andrade (29-0, 18 KOs), of Providence, Rhode Island, must fend off Williams to maintain the leverage he needs if he is ever to secure high-profile title unification fights against Gennadiy Golovkin (41-1-1, 36 KOs), the IBF/IBO champ, or Jermall Charlo (31-0, 22 KOs), the WBC champ.

“It’s a risky fight for both of us,” Williams said. “He’s the champion and I’m the number one contender. If he loses, the belt goes and that’s his status gone. But the same for me – I’m back to the bottom of the pile. There’s a lot at stake and neither of us will take a backwards step, and that’s what will make it a great fight.”

Williams has won seven consecutive fights since losing a majority decision to former WBO junior middleweight champ Liam Smith in their 12-round rematch in November 2017 in Newcastle, England. Andrade has not lost in 12½ years, not since he was eliminated in controversial fashion from the 2008 Summer Olympics in Beijing.

“The outcome is me winning,” Williams said. “Whether it’s over the distance or inside the distance, it doesn’t matter to me. As long as I take that belt back to Britain. I have no doubt about it. I’m super confident and I don’t think there’s any way that he beats me. I think I can knock him out.”

Andrade-Williams will headline DAZN’s stream Saturday from Seminole Hard Rock Hotel & Casino. DAZN’s coverage is scheduled to start at 3 p.m. ET.
