Joe Calzaghe wants veteran Glen Johnson to beat Clinton Woods in their IBF light-heavyweight title clash in order to set up a lucrative fight.
Calzaghe has reached a "provisional agreement" to fight Johnson if he wins, while there has also been interest from the Woods camp in a potential meeting.
"Maybe I want Johnson to win because he's a bigger name in America - he's knocked out Roy Jones," said Calzaghe.
"Woods would be a good fight but it wouldn't mean much worldwide."
Dennis Hobson, Woods' promoter, said he had offered Calzaghe £1.5m to move up to light heavyweight and face Woods.
Calzaghe, who normally fights at super-middleweight, said he viewed Woods v Johnson on Saturday as a "50-50 fight".
"Johnson is not getting any younger while Clinton has the title now so I think he has grown in confidence and he's improved slightly as a fighter," said Calzaghe.
"I honestly think it's a 50-50 fight."
Calzaghe unified the WBO and IBF super-middleweight titles against Jeff Lacy earlier this year and will return to action against Sakio Bika in October following injury.
