Promoter Eddie Hearn says Andre Ward has "no option" but to come to the UK to fight Carl Froch.
Ward was far too good for Froch when they met in Atlantic City in 2011, winning a comfortable and unanimous points decision.
Ward was ringside for Froch's epic fight with Mikkel Kessler on Saturday night at the O2, and appeared to keep the door open to coming to the UK for a rematch.
And Froch's promoter Hearn believes Ward has no option but to travel to England.
"Andre has absolutely no options. Tell me another fight out there for him at super-middleweight," he said.
"That's why he was at the 02 - he wants the fight with Froch. That's a massive fight.
"We're sitting here with two belts and Carl has just catapulted himself to huge new levels in terms of sporting prestige in Great Britain, so we'll relax and take our time.
"If Andre wants the fight, then it will have to be where we want it."
