The former UFC heavyweight champion admitted that he is a ‘major fan’ of his more famous brother Tyson Fury.
And the retired MMA fighter, 57, has even offered to help the Gypsy King’s younger sibling train for the bumper celebrity showdown.
YouTube badboy Paul, 25, recently confirmed that he will finally fight Fury, 23, at Madison Square Garden on August 6.
The pair were originally supposed to fight late last year before Fury – the youngest brother of world heavyweight champion Tyson – pulled out through illness and injury.
But now, after months of trash talk, both the date and venue have been announced – with Fury set to head overseas in a matter of weeks to fight in New York.
However, he will have to do so without the help of his father John, who is currently unable to enter the United States.
So with Fury potentially at a disadvantage for the biggest fight of his career to date, Rutten is ready to help him in any way he can if he wants it.
Rutten told Karate Combat’s official Instagram account: “I would love to train Tommy Fury, are you kidding?
“S**t, for the Fury family; I love Tyson. Major fan of this guy and I think [that] we can do some damage.
“Yeah, it would be great. I’ll be in the corner. Yeah, at least he has a cornerman.”
With a background in karate, Rutten famously used a wide stance to great effect in his MMA career, in a similar vein to the one that was adopted by ‘The Baddest Man on the Planet’.
And he feels Fury should do the same thing if he wants to stand a better chance of having success against Paul.
“I have a different style, it’s more of an open stance,” Rutten added. “And I think a lot of people are really not reactive to it.
“Tyson used to fight like that and was very effective with it.
“It gives you almost equal power in both left and right hands.
Rutten also insists that Fury should engage in mind games with Paul to gain a mental edge over his rival.
He continued: “I think if he can get inside his head and show a few things that I had and that I was very successful with against really good boxers in Holland.
“Then a guy like that who has already picked up really great boxing while he picks that up really fast and he’s going to use that to his advantage.”
