Warren slams 'difficult' Haye camp

Frank Warren has criticised David Haye’s camp for their failure to agree a heavyweight unification bout with Wladimir Klitschko.

WBA champion Haye and manager Adam Booth opened negotiations with the Klitschko camp over a fight between the Londoner and current IBF and WBO champion Klitschko after the Ukrainian pulled out of a fight with Dereck Chisora last month due to a stomach injury.
