The two will meet at the Imtech Arena in Hamburg on 2nd July, in a fight that Coral say will be the biggest turnover fight for two years.
“Although we make Klitschko the favourite, we expect to see a closely fought contest, and with betting available throughout the fight, the longer it goes the better,” said Coral spokesman Gary Burton.
“We expect business to exceed the Hatton Pacquiao fight of two years ago, meaning an industry turnover in excess of £5m,” added Burton.
Klitschko is 5-4 to win the bout by knockout and 7-2 to win on points. Haye is 15-8 and 8-1 to do the same.
