George Groves made short work of Italian Andrea Di Luisa on his return to the ring at London's Copper Box on Saturday night.
In his first fight since losing to WBC champion Badou Jack in September and with new trainer Shane McGuigan in his corner, Groves dominated the super-middleweight contest before claiming victory in the fifth round when Di Luisa's team threw in the towel.
The 27-year-old Londoner now boasts a record of 22 wins from 25 fights, with his other two defeats coming against Carl Froch.
Groves told Sky Sports 1 after the bout: "I'm really happy with the performance. I think I boxed really well. Obviously I'm gonna make a couple of mistakes, first time back in a little well, but I felt really sharp. I felt I dictated the pace from the get-go."
On life with McGuigan, Groves added: "I'm enjoying it. I think we're going to be a winning team."
