Fighting Andre Ward or Julio Cesar Chavez in Las Vegas could be an option for Carl Froch to consider.
Chavez, a former WBC middleweight champion, and unbeaten WBC super-middleweight champion Ward are considered as potential opponents for a fight in Las Vegas. Ward beat Froch on points in 2011.
After knocking out George Groves to retain his WBA and IBF super-middleweight titles at the weekend, Froch may postpone retirement to fulfil his dream of fighting in Las Vegas.
"I'm a very young 36," Froch told Sky Sports. “There's some steam left in this old train, and a couple of big fights if they're available.
"If I do fight again, which I dare say I probably will, it will be somewhere like Las Vegas because that's one thing I've not done. Every fighter would like to tick that box. It's the fight capital of the world.
"All the greats have boxed there and for me not to have done so, with all the things I've done, would be a crying shame."
Froch admits his career can get no better than his eight-round knockout victory against Groves at Wembley Stadium on Saturday night.
The 36-year-old WBA and IBF super-middleweight champion knocked out his fellow Briton to end his 12th world title fight in emphatic fashion in front of a crowd of 80 000, a post-war British record.
After the fight Froch said his 24th knockout victory was the highlight of his glittering career. He indicated he might hang up his gloves after saying the electric atmosphere at Wembley could never be topped.
But with time to contemplate his future outside the ring the Nottingham fighter said on Sunday it was likely he would bid to extend his 33-2 record.
Froch is taking a holiday before deciding his future. But is he fights again, his opponents and critics should not underestimate him despite his advancing years.
"The answer to those who doubted my age came last night," Froch said. "I've still got it.”
