Kostya Tszyu's manager Matt Watt has questioned the professionalism of promoters Frank Warren and Vlad Warton after continuing conjecture about a fight between the International Boxing Federation super lightweight champion and mandatory contender Ricky Hatton.

Watt and Tszyu have spent much of the last two weeks denying the Australian fighter has signed to defend his title against Hatton in the Englishman's home city of Manchester next year.

Warren insists he has done a deal with American pay television network Showtime for a fight between Tszyu and Hatton in April or May.

Bombarded from calls from Australian journalists seeking confirmation of the fight, Watt has repeatedly stated Tszyu has yet to see, let alone sign a deal, with Warren.

English promoter Warren has been dealing with Tszyu's American-based promoter Warton, but neither has had any recent contact with Watt.

Watt said he had not held any discussions with Warren and it had been at least three weeks since his last conversation with Warton, though in that time there had been "written correspondence of a very generic, non-specific nature" between the two of them.

Watt said he was waiting for Warren or Warton to explain why it made sense for Tszyu to fight in the challenger's backyard at a proposed local time of 4am to accommodate American and Australian television schedules.

He stressed he did not want to enter into a slanging match with the promoters but was clearly frustrated by the lack of communication.

"Kostya Tszyu is pound for pound one of the leading boxers in the world and needs to be promoted accordingly," Watt said.

"That would include regular and clear communication which does not appear to be happening at this time."
