Carl Froch has challenged Andre Ward to a WBA super-middleweight unification fight in Nottingham.
Ward beat Froch on points in the final of the Super Six tournament in Atlantic City, but he has only fought twice since that win three years ago.
Froch has reportedly been toying with the idea of retirement after he beat George Groves last year, but he seems to have his heart set on one final mega fight with Ward.
He told reporters: "I fought him in the US. Now it's only right that he comes over here. To be a truly great champion you have to box overseas. Ward needs to be forced to travel out of his comfort zone.
"I dare him. He will discover that I'm a very different animal here than I was that night on the Boardwalk."
Froch, who has only lost twice in his professional career, has a record of 33-2.
