"It's the same from the last press conference, he's focused and I'm focused," 'The Destroyer' exclusively told Sky Sports.

"People are saying that I'm not focused because I bought a little bit of jewellery, the material stuff that I always wanted.

"I'm still hungry, I still want to prove people wrong, everyone's saying it was a lucky shot that beat him, AJ's saying it was a shot from the gods.

"We'll be in there with the same mentality, a lot of people are still doubting me. Only Joshua and my opponents know what I am like inside the ring.

"It's all eyes on me right now. He wants his belts back, he's going to have to fight hard, it won't be an easy fight for either of us. I see it in his eyes, it's giving me more motivation and confidence. December 7, the belts are in the air and the best man wins."

IBF, WBA and WBO title-holder Ruiz Jr, wearing a sombrero, only broke from an intense face-off when he heard calls of "let's go champ" from the onlooking Shannon Briggs, the former heavyweight champion from New York.

Joshua earlier said: "In my short 11-year career, from the amateurs to the pros, I've seen a lot. I wouldn't say I've seen it all, but I've definitely seen a lot.

"There were times when I faced defeat as an amateur. My third fight. Imagine I stopped then, there would be no now. I lost in the European Championship quarter-finals. Imagine I stopped then, there would be no now.

"I lost in the World Championship finals. Imagine I stopped then, there would be no now. Stopping isn't in my DNA. As long as I have breath, I will keep fighting for the passion of boxing and more so as an ambassador for championship-level fighting. That's where I belong.

"I was born with a fighting spirit. I know how to fight. People say, 'you lost your titles'. I say, 'to lose something is to never get it back'.

"I have a second chance on December 7. I didn't have a warm-up fight, I'm not gun-shy.

"Shannon Briggs talks about the times he was down and out, and nobody believed in him.

"That's where 'let's go champ' comes into my life right now."

Joshua then called on Briggs to shout his catchphrase and he responded with a loud: "Let's go champ!"
