BOXING: David Haye’s $40million super clash against Wladimir Klitschko is at the centre of a bidding war between seven countries.

WBA world heavyweight champion Haye is due to face IBF and WBO king Klitschko on July 2, and the only detail missing from the signed contract is where it will be staged.

Haye’s Manager, Adam Booth, said “Ideally the venue will be in Europe and indoors because we don’t want to have to worry about it raining.”

Stadiums in countries as diverse as the United Arab Emirates, Switzerland, Monaco, Germany, South Africa and the United States have all demonstrated serious interest.

Haye is contracted to fight either the younger Wladimir or his 39-year-old brother Vitali, who successfully defended his WBC title in Cologne on Saturday against Cuba’s Odlanier Solis.

Vitali’s name was put in the contract as cover, for there is a doubt over Wladimir’s ability to beat a stomach muscle injury that forced the cancellation of his April defence against London-based Dereck Chisora.

Booth added: “They have to nominate which brother it’s going to be around the start of May.”
