All Black and heavyweight boxer Sonny Bill Williams believes that fellow cross-code convert Sam Burgess will become a rugby union great.
Burgess, 26, moved from rugby league to union last year, but is still adapting to the game and endured a difficult international debut on Friday as the England Saxons battled their way to a win over the Irish Wolfhounds.
"Sam is a world-class athlete and I have got no doubt that whether he makes it at number 12 or number six he is going to make it," Williams told Rugby Heaven.
"I am no expert but, like I said, he is a world-class athlete, he has got a hard work ethic and he will be hurting after performances like that if he didn't play too well but never back against someone of his talent."
Burgess, who joined Bath last year, is in Stuart Lancaster's training squad for England's opening Six Nations clash with Wales on Friday.
