ANTHONY MUNDINE has broken his silence on his ties with Greg Inglis, promising to offer the Melbourne Storm superstar the same "help" he provided renegade Bulldog Sonny Bill Williams.

Mundine, Williams's confidant and co-manager, cleared the way for the Kiwi league international's controversial move to French rugby club Toulon when he coughed up $750,000 of his own money to settle with the bottom-placed NRL club.

Now there are fears Inglis could be the next superstar to leave the code due to his close friendship with the boxing champion.

Asked if he would take over the management responsibilities of Inglis, Mundine told The Sun-Herald: "It's up to Greg."

"Definitely, if he wanted help, I wouldn't knock it back, just like Sonny.

"Obviously me and [fellow agent] Khoder Nasser have promotions, management, all that kind of jazz.

"We just try to look after the boys who want to be down with us."

Inglis is managed by Allan Gainey and contracted to the Storm until the end of 2010, but there are growing fears he could join Williams, Craig Gower, Mark Gasnier and Luke Rooney in French rugby.

Mundine predicted more NRL players were likely to follow unless the NRL did more to retain its elite talent, saying Inglis "could be earning a lot more than what he's earning now" overseas.

"It [joining Team Mundine] is up to Greg and him being happy, it's the same as it was with Sonny," Mundine said. "I don't put any pressure on him, I just try to help him and be there for him.

"That's something you've got to ask Greg. What I will say is I will always be there for him.

"If he ever needs me, I'll be his brother's keeper. If he wants me to hold it down for him, that's no problem.

"Decision-wise, Greg Inglis is his own man.

"The players are getting a lot smarter than what they were. A lot of them weren't [informed] about the money situation [in the NRL], management and things like that.

"They're starting to know the game is making a lot more money and they ain't reaping the benefits.

"I think if the NRL doesn't make a change for the better then it's going to come back to haunt them."

The former five-eighth turned boxer met Inglis during the 2005 State of Origin series, although the Inglis and Mundine families have a history.

"My uncle knocked about with Greg's dad in the '70s," Mundine explained.

"He's obviously from the North Coast and my dad's family is from the North Coast. We're not cousins but we're cousins of cousins, if you know what I mean.

"He [Inglis] will call me now and then if he feels he's got a problem or he wants some advice."

Gainey said the close relationship between his client and Mundine was not a concern.

"None at all - he [Inglis] doesn't break contracts," Gainey said.

Mundine, who is eyeing off The Contender contestant Peter Manfredo jnr or fellow American Kassim Ouma as his next opponent, explained his role in Williams's move to France.

"We don't go out scoping for players, we don't have recruitment agents that do that," he said of his management team with Nasser.

"We just help our brothers. Sonny was a close friend and brother and it was known he needed help.

"He came to us for advice and it progressed from there.

"Then he said he wanted for Khoder and me to look after his affairs and we said, 'No problem, we've got your back'."

Asked about speculation Williams wanted to convert to Islam, Mundine said: "A lot of that is talk, gossip and rumours. Speculation.

"As far as that is concerned, I don't know. He's never discussed it with me."
