Kayla Harrison's coach says Amanda Nunes has beaten every champion at 135 'except for Kayla'

Mike Brown, who worked with Nunes for a handful of fights at American Top Team, says he would consider Harrison the greatest of all time if she beats Nunes at UFC 334 on Saturday.

Kayla Harrison's head coach Mike Brown says Amanda Nunes has beaten every bantamweight champion apart from Harrison, and that he would consider Harrison the greatest of all time if she wins their UFC 334 title fight.

"Amanda's beaten every champion I believe at 135 except for Kayla," Brown told MMA Fighting. "She's beat every champ that's ever been at the weight. That's pretty damn impressive except for Kayla. Obviously, she's done more in the sport than Kayla, but Kayla's record is near perfect."

Brown pointed to Harrison's one defeat, to Larissa Pacheco in their third fight after she had beaten her twice. "She's clearly head and shoulders above the competition," he said, adding: "I would consider her the greatest of all-time if she wins this fight."

Brown coached both women at American Top Team, but said their shared past there has little to do with Saturday's fight. "It's a big gym. There's a lot of training partners. They weren't training partners that often. Very seldom," he said. "I trained with Amanda, but I was never her official head coach. But I did work with her for a handful of fights. But this is business."

He added that neither camp holds any secrets: "Amanda's a big power puncher and everyone knows that. Kayla is a world class grappler and a multiple world champion, a world champion in judo, so there's no secrets in what each fighter's going to want to do."

Nunes, who retired after beating Irene Aldana at UFC 289 in June 2023, has said she walked away burned out. She challenges Harrison for the bantamweight title in the UFC 334 co-main event at Madison Square Garden on Saturday 14 November. The main card starts at 2am UK time on Sunday morning.
