Adam Booth, manager and trainer of WBA heavyweight champion David Haye, has fired back at WBO/IBO/IBF champion Wladimir Klitschko. During a recent interview with BBC Sport, Klitschko said he was still willing to fight Haye on a previously discussed date of July 2 in either Germany or England. According to Booth, there has been no contact from Klitschko or any individual from his camp since the month of December. Haye is set to return on May 21. Klitschko is going to fight unbeaten British champion Dereck Chisora on April 30 in Germany.
