LAS VEGAS – After her spectacular rise to the top of the UFC’s women’s bantamweight and featherweight divisions, dual world champion Amanda Nunes in the best form of her career as she prepares to defend her UFC bantamweight title at UFC 239.

Nunes (17-4 MMA, 10-1 UFC) will take on former UFC bantamweight champion Holly Holm  in the co-main event at T-Mobile Arena on Saturday night, and the 31-year-old brimmed with confidence after working out for the fans at the MGM Grand.

“After the best fight of my career, I feel like I’m ready for everything,” she said. “Holly’s a tough fight, but I feel like I’m way in front of her in this game and I will prove it on Saturday. I’m the best in this game and I will keep improving. I will keep this belt for a while and I’m 100% sure I will walk away with my new belt.”

Holm (12-4 MMA, 5-4 UFC) is looking to recapture the 135-pound title she won from Ronda Rousey in spectacular fashion back at UFC 193. And Nunes said she will need to be on top of her game to ensure the former champion isn’t reunited with the title.

But while Nunes said she’s sure Holm will arrive on fight night well drilled and armed with a solid gameplan, the Brazilian said she’ll be ready to claim victory, regardless of how the bout pans out.

“Honestly, Holly is a very smart fighter,” she admitted. “I have to be sharp everywhere, wait for the best moment, then finish the fight as fast as possible. Whatever happens, my hand’s going to be raised that night.”

Nunes looked happy, relaxed and totally at ease with her place as the premier female fighter in the UFC. And she revealed the key to victory for her latest title defense isn’t a technical tweak or a specific gameplan. It’s simply a case of being happy when she steps into the octagon.

“Having fun inside the cage,” she said. “I’m the best, and I will prove it Saturday.”
