The conventional wisdom is that a boxer risks ill fortune and toys dangerously with distraction if he so much as thinks about the next opponent after the one about to come gunning for him out of the opposite corner. Let alone talks about it.
But then, as the self-described chubby kid, Andy Ruiz Jr has been defying the preconceptions of prize-fighting since his father took him to a gym at the age of six and he started beating up older and taller boys.
So he has no hesitation in revealing that he and Deontay Wilder are negotiating a mega-bucks super fight for the undisputed world heavyweight championship, even as he readies himself to defend the titles already in his possession in his desert rematch against Anthony Joshua this Saturday night.

'Yep, it's all arranged,' says the rotund Ruiz, who came out of nowhere to spring one of the most amazing upsets in the annals of the ring by knocking out Joshua in New York this summer.
Of Wilder, the Bronze Bomber whose explosive fists knock down all who dare to challenge for his WBC title, Ruiz says: 'Deontay's a good friend of mine.
'We talk on the telephone all the time.'
For their grand design to become golden reality, not only must Ruiz beat Joshua a second time but Wilder has to win the February rematch of his epic draw with Tyson Fury.

Mere trifles, apparently.
Ruiz points out that both he and Wilder are promoted by Al Haymon, the financial shadow boxer who pulls the purse strings for Mister Money himself, Floyd Mayweather.
'Al's told us the plan,' he says.
Whatever Al wants, Al is in the habit of getting for himself and his stable.
Ruiz attended numerous events in his native Mexico following his victory over Joshua in June

So Ruiz feels at ease blowing a nought or two off the first seven figure paydays of his career.
'Being rich and famous is going really well,' he says with his ever-ready chuckle as he reaches out for the $13 million cheque written in Saudi Arabian oil which will more than replenish however much has been spent so far of the $5 million bite he took out of the Big Apple six months ago.
Moments after he turned Joshua's world upside down Ruiz called out to his mother: 'Mum, we don't have to struggle any more.' Senora Ruiz was wreathed in smiles as she waved back from the madding crowd.
Not only had her laughing boy secured the family fortunes but she and most of their many relatives had snaffled ten thousand dollars each by backing him at 11-1.
Ruiz won four world heavyweight title belts, and makes his first defence on December 7
The journey from a dusty border town to the wealth which comes with being the first world heavyweight champion of Mexican origin was complete. Almost.
All that remained was a car ride. As soon as he arrived back home in the southern Californian town of Imperial he borrowed a flash convertible and drove down the main street through cheering crowds, brandishing aloft those glittering belts.sonos sonos One (Gen 2) - Voice Controlled Smart Speaker with Amazon Alexa Built-in - Black read more
A couple of days later he went and bought his own high-end methods of transport. A white Rolls Bentley and a Porsche Panamera. The spree has continued with purchases of two brands of top-of-the range G-wagons and a Lamborghini.
