Frank Warren has vowed to set up a rematch between bitter rivals George Groves and James DeGale after announcing the shock news that the British and Commonwealth super-middleweight champion has joined his promotional stable.

Groves has signed a three-year deal with Warren in the hope that the promoter will secure him the world title shot that he craves. The move will see the unbeaten Groves leave the Hayemaker promotional stable but the 23-year-old will still be trained by Adam Booth, the man Warren once described as "the most difficult person I have to deal with in all my time in boxing".
