George Groves has employed Shane McGuigan as his new trainer as he tries to revive his career as an elite super-middleweight.
Groves lost a split decision against US-based Swede Badou Jack for the WBC world title in Las Vegas in September and then split with trainer Paddy Fitzpatrick. The Londoner had suffered defeats to Jack and Carl Froch (twice) while Fitzpatrick was in the corner and felt he needed a change.
Groves (21-3, 16 KOs) is due to return to action against Italian Andrea Di Luisa (18-3, 14 KOS) at the Copper Box in London's Olympic Park on January 30 when McGuigan will be in the corner for the first time.
"I am happy and excited to be back and to be joining a new, exciting and dynamic team of young hungry fighters with a fantastic trainer," Groves said.
''I've found the past few weeks working with Shane rejuvenating. I'm back punching hard, enjoying my boxing and am now eager to get back to winning ways.
''The loss earlier this year to Badou Jack was a close and frustrating one and I hope to avenge that defeat as soon as possible; starting on January 30 with a KO win."
McGuigan also trains IBF super-bantamweight champion Carl Frampton and former world heavyweight and cruiserweight champion David Haye at his Battersea gym.
McGuigan is the son of former world featherweight champion Barry McGuigan and is only 27 - the same age as Groves - but has already guided Frampton to world title glory.
