David Haye should rebuild his career in America before targeting a clash with Vitali Klitschko, according to Golden Boy Promotions chief executive Richard Schaefer.
Haye is reconsidering his retirement plans following his overwhelming points loss to Wladimir Klitschko in Hamburg on Saturday night.
Schaefer still believes the 30-year-old is the most exciting fighter in the heavyweight division even though he fell well short of expectations at the Imtech Arena.
"I was disappointed by David's performance. He didn't really try to win the right, press the action or go for the knockout," he said.
"I was surprised at how negative he was, but maybe it was the people around him who were negative as well and that filtered down to the fighter.
"I've read that he wants to retire, but if I was him I'd go for a couple of fights in the US against guys like Chris Arreola or Tomasz Adamek.
"He should get a couple of wins and then give it another go.
"He still has a future as a heavyweight because he's still the most colourful guy in the division.
"Just because he had one disappointing performance, I don't think it's fair to judge him on that.
"I believe Haye still has unfinished business in the heavyweight division.
"He has the charisma, punch and will have learnt from that mistake. He's still only 30, which for a heavyweight is young."
Golden Boy, founded by Oscar De La Hoya, co-promoted the show in Hamburg but had advised Haye to fight Vitali, not Wladimir.
Vitali is generally perceived to be the more dangerous opponent, but Golden Boy felt he was better suited to Haye's strengths.
"Oscar De La Hoya and our matchmakers actually liked Vitali more than Wladimir," said Schaefer.
"That's because Wladimir's the more athletic one while Vitali's more robotic and has greater difficult moving.
"David's strength is his athleticism, movement and speed. That would be magnified against Vitali, because Vitali is so mechanical.
"I don't like to inject myself if I feel like my opinion is not wanted. If they (Hayemaker) want to do it by themselves, then let them.
"We did mention what we thought to (Haye's trainer) Adam Booth."
Schaefer was unmoved by Wladimir's performance and scathing of the Ukrainian brothers' reign over the heavyweight division.
"It takes two to tango...did anyone think Klitschko's performance was exciting? I wasn't impressed by him," he said.
"If he's that strong, mean, beast from the east, he should have gone for the knockout. He didn't.
"Why didn't he take more risks? Because he was winning and if you fight with that mentality you'll be known as a boring fighter, which is what he is.
"In the States do you think anybody cares about the Klitschkos?
"They have dominated the division but people couldn't care less about them.
"To be the heavyweight king you should expect more than just winning. I'd still rather watch David Haye than either Klitschko."
Schaefer was also critical of Haye's decision to go public with his broken little toe, which he blamed for his defeat.
"I wouldn't have shown the little toe had I been there. It's ... the little toe." he said.
