David Haye insists his fight with Nikolay Valuev is just another step towards his ultimate goal.

The pair clash on November 7 with Valuev's WBA title up for grabs, but Haye admits he already has one eye on future tests to come once he's dealt with the "Beast From The East"

"My job is to knock out Nikolai Valuev and become the heavyweight champion of the world. I will be the first British champion since Lennox Lewis and that has always been my aim, to be a two-weight world champion," Haye told Sky Sports News.

"I was undisputed cruiserweight champion and my plan is to go up in weight and do what only one other fighter in history has done - that's Evander Holyfield - and then become the undisputed world heavyweight champion. The Valuev fight is the next step."

Haye had to pull out of a scheduled showdown with IBF/WBO king Wladimir Klitschko in June, but says things have worked out for the best.

"I was due to fight Wladimir Klitschko but picked up a back injury and that fight will have to wait for next year. It works out quite well though as by the time we fight each other it will be for a unification of the world heavyweight championships."

Haye is not underestmating the giant Valuev, the tallest and heaviest champion in the division's history.

"He's the WBA heavyweight champion of the world. I said from day one I want to be world heavyweight champion so I'll go up about eight stone and fight the biggest champion in history," he added.

Preparations won't be easy for the British boxer trying to replicate the sort of problems Valuev will pose.

"You've got to get the biggest sparring fighters you can find, " added Haye.

"Valuev is seven foot two so I will struggle to find someone that big who can spar with me but I'll find guys who are six foot seven, six foot eight and then adjust when I get into the ring."
