Tony Bellew has insisted he will continue to fight and has targeted Tyson Fury and Andre Ward as potential future opponents.
The 35-year-old stopped David Haye in five rounds in their rematch at London's 02 Arena, dropping the former WBA heavyweight champion three times.
Bellew's trainer Dave Coldwell and promoter Eddie Hearn revealed they would also like their fighter to retire, given two big purses against Haye followed him having achieved his ambitions of winning a world title and fighting at Everton's Goodison Park.
Despite his victories and the fact he continues to improve, Bellew recognises his size compared to that of reigning world champions Anthony Joshua and Deontay Wilder means they are too big and powerful for him to challenge.
He regardless considers the less powerful Fury a worthwhile risk and believes American Ward - a world champion at super-middleweight and light-heavyweight - can be tempted out of retirement.
"It's hard when you've had your defining moment in this sport. What am I chasing?," Bellew said.
"I don't know. I like fighting and challenges, and I've definitely got a screw loose, so I'll keep fighting until the screw detaches itself. "I'm not stopping now.
"See if I can talk (wife Rachael) round and we'll go from there. That's my biggest fight."
