James DeGale would welcome a rematch with George Groves if their showdown turns out to be a classic.
The London rivals, former amateur stablemates at Dale Youth ABC, meet at the O2 Arena on Saturday for the British and Commonwealth super-middleweight titles.
DeGale, 25, believes the showdown will be over quickly if Groves' temperament fails him, but is willing to meet his bitter foe in a rematch if fans demand it.
"I hope George comes to fight, but going on his last fight I don't think he will," he said.
"I've known George for years - as soon as I hit him he'll see the red mist and will try to fight.
"Once I've outboxed him after four or five rounds, he'll have to come for me. If he comes to fight me, I don't see it lasting long. My defence and punch power is too much.
"If he wants to be Mr Technical and do what he did against Kenny Anderson, which was rubbish, it could last a couple of rounds longer.
"If I get drawn in, then and only then could it be a great fight.
"I don't see it happening, but if it is a good fight then of course we'll do it again."
DeGale has been trash-talking Groves, who won their only meeting as amateurs, since the fight was announced.
And he has now added the 23-year-old's trainer Adam Booth, who also coaches WBA world heavyweight champion David Haye, to his list of targets.
"As a professional George has got worse. He was better in his first three or four fights," said the Olympic gold medalist.
"I don't know why he's gone backwards - maybe it's his training or his trainer.
"Adam Booth is just a glorified Fitness First coach.
"I don't rate him as a trainer. I heard he boxed as an amateur, but pulled out of a lot of fights."
