Andy Ruiz Jr warned Anthony Joshua that he wants keep his belts for a long time ahead of their rematch in Diriyah, Saudi Arabia later this year.
The rivals went face to face for the first time since Joshua was surprisingly beaten by Ruiz Jr in the country that will host their rematch.
“The hunger still remains,” Ruiz Jr said ahead of defending the IBF, WBA and WBO titles that he took from Joshua.
“I don’t want 15 minutes of fame. I want it to last. I want a generation. I want to be a champion for more years.
“Two big heavyweights punching each other in the face, it’s going to be exciting.
“I know Anthony Joshua is coming hard, he’s coming strong. He’s more hungry, he wants his belts back. He’s preparing hard, but so am I.
“There’s a lot of responsibilities. I’m going to try my best. I’m going to keep those belts and I’m going to have them back in Mexico.
“I’m going to win here in the same fashion that I won on June 1.”
Joshua was floored four times and beaten in seven torrid rounds by Ruiz Jr on his US debut in New York.
The surprise result ended Joshua’s unbeaten record, his world heavyweight title reign and his hope to fight Deontay Wilder to crown an undisputed champion.
“I was up against a good challenger. Andy is champion now,”Joshua said at the press conference.
“That will last until December 7 when he puts his titles in the air. Two warriors to go war and the best man will walk out victorious.
“Being a champion is more than the belts. It’s about a championship mindset. The belts will go up in the air and we will fight for them again.”
