American great Bernard Hopkins has been told to ignore the challenge of Joe Calzaghe in favour of settling an old score with Roy Jones Jr.
Hopkins believes he could "easily" beat Calzaghe
Hopkins lost a middleweight fight with Jones in 1993 before embarking on a 12-year unbeaten run in that division.
His trainer, Nazim Richardson, ideally wants the 43-year-old to retire, but he says a re-match with Jones would mean more than a clash with Calzaghe.
"It's the fight which the US would prefer to see," said Richardson.
"Bernard has accomplished everything he needs to accomplish in this sport and I have been telling him for a long time that he should stop fighting.
"But I can see why a fight against Roy Jones would mean so much to him. It is all about settling the score after their fight in 1993."
Hopkins has already vowed to give Calzaghe a "free facelift" if a proposed fight goes ahead at light-heavyweight next year.
Undefeated Welshman Calzaghe, 35, called out Hopkins after beating Mikkel Kessler in Cardiff earlier this month to become the undisputed world super-middleweight champion.
Calzaghe's promoter Frank Warren has already opened talks with Hopkins' representatives, Golden Boy Promotions, over a possible super-fight across the Atlantic in the spring.
The notoriously tough negotiator Hopkins has already ruled out coming to Britain to fight, and cited New York's Yankee Stadium as his venue of choice.
"Bernard does not see any reason why he should travel to Calzaghe's back yard," added Richardson, who has been training Hopkins for the past two years.
"He is the great fighter and he has earned the right over the years to make his choice.
"Calzaghe is a good fighter but there is a big difference between the two of them.
"Everyone built up Kessler but who had he really beaten? Where are the living legends on Calzaghe's record?
"The mark of an all-time great fighter is the fights he has had against other living legends. Bernard has fought Jones and beaten Felix Trinidad and Oscar De La Hoya. He is a class apart."
