Haye made an impressive debut in the heavyweight division
Londoner David Haye believes his first-round demolition of Polish heavyweight Tomasz Bonin has made it more difficult for him to get matched.
Haye, 27, knocked out Bonin on his heavyweight debut in April 2007 but is still searching for an opponent for his next bout on 15 November.
"They won't want to get knocked out, they realise how much power I have," he told BBC Radio Merseyside.
"I'm a natural heavyweight, so that won't help my chances."
Since beating Bonin, Haye has become the recognised undisputed cruiserweight world champion with wins over Jean-Marc Mormeck and Enzo Maccarinelli.
It's just a matter of getting in there, knocking these big heavyweights out and getting in line for [Wladimir] Klitschko
And Haye added: "I think I'm ready for [IBF and WBO heavyweight champion] Wladimir Klitschko now.
"But in terms of rankings and raising my profile in the States I think I'll need a couple of fights.
"On the promotional side of it I think that'll be a good idea as well so I'm not just coming in as cruiserweight champion but as a heavyweight contender."
Haye is confident a deal to fight the Ukrainian can be reached.
He said: "I've got good rankings already, the heavyweight organisations see me as the main man in the division.
"It's just a matter of getting in there, knocking these big heavyweights out and getting in line for Klitschko."
Since starting Hayemaker Promotions, the Bermondsey man has signed three fighters from Merseyside - featherweight Derry Mathews, lightweight John Watson and super-middleweight Tony Dodson.
Haye is a long-time friend of Dodson and he believes the former British champion could surprise a few people.
"If he gets the regular fights he can produce the goods, people won't be expecting much out of him but he's definitely our ace in the pack," said Haye.
