George Groves has continued his war of words with Chris Eubank Jr. by claiming that he would have beaten his father Chris Eubank Sr. if they had met in the ring.
Groves, 29, will make a second defence of his WBA super-middleweight title at Manchester Arena on Saturday night when he meets former sparring partner Eubank Jr. in the semifinal of the World Boxing Super Series.
The Londoner has frequently criticised his opponent's preparations for the fight, accusing the former middleweight of copying the same mistakes he made in the build-up to his 2014 rematch with Carl Froch -- which ended with Groves losing by knockout.
Groves jibes have also extended to Eubank's father -- a former two-weight world champion who now works closely with his son.
When asked if he would have defeated Eubank Sr., now 52, in the prime of his career, Groves replied: "I haven't seen much of him, but I'm sure I would have. He had enough losses on his record and I don't fall for his bulls---.
"His two fights I've watched most closely were those defeats by Steve Collins, who beat him in every minute every round. Senior didn't fight like that. He was about posturing and being heavy-handed.
"Back then his gimmicks annoyed some of his opponents, who fought him with their emotions. I keep mine out of the ring so I wouldn't have made that mistake. Probably he wasn't much of a trainer so maybe he wouldn't have survived in this era."
Speaking to reporters ahead of Saturday's matchup, Groves also cited Eubank Sr. as the reason he stopped sparring with his son.
Eubank Jr., was brought in to Groves' camp by former trainer Adam Booth in 2011 while he was preparing for his highly-anticipated fight with James DeGale -- which ended in victory.
"He was available and cheap," Groves explained. "The dad was a good test of my mental stability, that's partly why Adam Booth brought him in. He was worried if I could keep my composure and thought if I can put up with the dad, I'm mentally strong.
"The son was brilliant. He would come in moody, do his rounds and leave.
"Ultimately, I stopped sparring Junior because I couldn't put up with the dad. It wasn't worth it to put up with the rubbish which came out of his mouth."
