Danny Williams plans to take on British heavyweight champion Matt Skelton after winning the Commonwealth title by split decision over Audley Harrison.
He had been set to meet Skelton in July before pulling out through illness.
"I'd like to go straight to a world title shot, but that wouldn't be fair. I have unfinished business with Skelton," said 32-year-old Williams.
Williams also revealed he had secretly prepared for the Harrison fight without trainer Jimmy McDonnell.
The experienced McDonnell was in his corner for Saturday's fight and staged sessions for the press in the build-up to the showdown in London.
But Williams was determined to do things his own way.
"I wanted to try something different so I did everything on my own, all my fitness training. I even laced up my own gloves for sparring," said the Brixton fighter.
"I won't be doing it again though. Next time, I'll be back with Jimmy."
Disconsolate Harrison, 34, shrugged off any talk of retirement following his first professional loss.
The former Olympic champion said he could take positives out of the defeat and would come back stronger.
"It wasn't my day at the office. Fair play to Danny, his hands were raised as the winner," he said.
"But I wasn't at my best, I hurt my hand in round two or three, picked myself up from my first knock down in round 10 and still forced a split decision.
"One loss is not the end of anyone's career."
Angling for a rematch with Williams, Harrison promised to "settle the score" next time.
But Williams and promoter Frank Warren - who was celebrating 25 years in the sport - were cool on the prospects of a return bout.
"We are looking at Williams v Skelton in March or April," said Warren.
"We need to find out who is the best in Britain."
Skelton must first get through a mandatory defence of his British belt against top-ranked contender Scott Gammer on 28 January.
He retained his British heavyweight title with a first-round stoppage of John McDermott on Saturday's undercard at the ExCel Arena.
