Paul Gallen wants a crack at him and now Danny Green is keen to take on Sonny Bill Williams in the ring.
Green, the Australian who has held world titles in the super middlweight, light heavyweight and cruiserweight divisions, approached Williams' manager Khoder Nasser about the possibility of a fight in 2016.
"A lot of people have been saying it to me and I said to Khoder I'd do it, no problem," Green told the Daily Telegraph. "He said that's not the stupidest thing I've heard. So we spoke about it. That, to me, is really exciting. It's a big fight.
"It's new, it's fresh, and Sonny Bill, man, look at the bloke. He's a giant, he's an exceptional athlete, I've got a lot of respect for the bloke."
Green would need to fight at heavyweight, allowing Williams to fight at a comfortable 106-107kg. Green would be closer to 87kg.
