George Groves has turned to trainer Shane McGuigan to ignite his career after three failed world title attempts.
Groves, who has 21 wins in 24 fights, dropped a split decision to Badou Jack in Las Vegas in September and twice failed to last the distance against bitter British rival Carl Froch.
The 27-year-old Londoner returns to the ring on January 30 when he faces Italian Andrea Di Luisa at the Copper Box and joins Carl Frampton and David Haye in McGuigan's stable.
''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," Groves said.
''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.
'I'm confident that now with the right coach I will reach the very top of the sport."
