I hardly follow boxing nowadays but this match up has got me interested due to the massive difference in size and weight ...
So does Haye really have a chance of knocking him out?Haye, 28, is eight stones lighter and nine inches shorter than Valuev.
He said: "David only needed a slingshot and stone to flatten Goliath, my right hand generates more power than that."
Valuev, who is 7ft tall, has yet to be floored or knocked out in his 16-year professional career and has lost just once in 50 fights.
But Haye, who has also lost just once in his career, said: "I am thrilled to announce that my dream of becoming world heavyweight champion will be realised on 7 November, when I challenge the tallest and heaviest champion of all time.
"I can't wait to step into the ring and prove that size doesn't matter. Mark my words: I will be the first man to knock Nikolai Valuev out."
