Floyd Mayweather plans to work with Anthony Joshua ahead of his £200million mega-fight with Tyson Fury.
Mayweather was ringside last December to watch Joshua retain his heavyweight world titles by knocking out Kubrat Pulev.
He was heard offering tactical advice during the fight and visited the champion's dressing room afterwards.
And as Joshua and Fury finally put pen to paper on their proposed undisputed fight, Mayweather revealed he will reunite with the once-beaten Londoner.
"I look forward to working with Joshua real soon, we talk all the time," he told the Disruptive Entrepreneur podcast .
"It's a very interesting fight. Anthony Joshua has a lot of experience and Tyson Fury as well has a lot of experience but with Anthony Joshua losing a fight [to Andy Ruiz Jr], it helped him become stronger.
"I met Tyson Fury on a few occasions; he's great guy and very interesting. After the fight I like to see him sing... I haven't seen him fight a lot of times.
"I've seen him fight twice, against Deontay Wilder, but it's a very intriguing match-up. You can never say what's going to happen in the sport of boxing. Both guys are great competitors."
On Monday, promoter Eddie Hearn announced Joshua and Fury have signed a deal for two bouts.
Hearn told ESPN that a venue for the fights, in which Joshua's WBA, IBF and WBO titles and Fury's WBC belt will be on the line, is set to be confirmed "within the next month".
Confirming the deal, Hearn said: "The hard part is always getting everybody to put pen to paper.
"But this was a major effort from all parties to get this over the line. You had rival promoters, rival networks and rival fighters.
"We've already had approaches from eight or nine sites. The offers have come from multiple countries in the Middle East, from Asia, Eastern Europe and America."
The deal is understood to represent a 50-50 split for the first fight, with the winner taking the larger 60 per cent share for a rematch.
Hearn's announcement comes just days after Fury insisted the fight against Joshua was "nowhere near" being made.
Fury added that he had stopped training and was drinking up to 12 pints of lager a day.
Fury said: "Until I've got a date and a load of money in my pocket, there's no fight.
"There's a lot of things going on that people don't know behind the scenes that can scupper a fight like that. We're nowhere near at the moment.
"I've stopped training now, I'm on holiday. I'm doing anything between eight to 10 to 12 pints of lager a day at the minute - I'm not eating though, so I'm just getting my calories through alcohol."
