Frank Warren says David Haye has gone too far with his claims that he'll decapitate Wladimir Klitschko.

Haye faces Klitschko in a massive heavyweight unification fight in Hamburg on Saturday night and the Englishman has provided plenty of talking points during the build up to the bout.

Warren is looking forward to the fight but he feels talk of putting people in hospital is "indefensible'.

"Of course it's gone too far. I don't recall too many boxers talking about putting people in hospital," he told talkSPORT.

"Can you imagine how the likes of Michael Watson and Gerald McClellan, who actually wound up in hospital, must feel hearing stuff like that? It's indefensible. Boxing is a dangerous sport and we don't need idiotic comments like that.

"This fight is a good fight, it's a stand up fight, it's a fight the heavyweight division has been crying out for. Get it on, it doesn't need all this nonsense. It's wrong. He does it before every fight. He's going to cut someone's head off, he's going to do this and do that, it's just ridiculous.

"I don't know why he does it - maybe he thinks that's the way to do it. The other side of the coin is that it has got him some sort of attention, but is it the right sort of attention? He's got a couple of blue chip sponsors, but will they want to be involved with him at the moment?

"The boxing board of control are a disaster area as far as that is concerned. They have let him get away with it time and time again without doing anything.

"It seems to me they are happy with the sanction fee and then doing nothing about it.

"What message does that send out to young fighters? Our business is a much maligned sport and it's things like this that give the knockers all the ammunition they need."

Warren thinks Haye will find the bout with Klitschko a step too far.

He added: "David Haye has done well in all of his fights so far, but this is a different type of fight. He can't fight Klitschko like he fought Valuev, where he was on the back foot for the entire 12 rounds.

"He can't do that with Klitschko because he's a better boxer, he's certainly more mobile than Valuev was and he can't do what he did to Audrey Harrison."

"He's got to take the fight to Klitschko and use his speed and get under Klitschko's jab, let his shots go inside and get away. If he can do that, can he do it for 12 rounds?

"If he can't, he'll be on his bum. I think Klitschko will be too big for him, he's a much improved fighter. In Germany he'll have the crowd against him, it'll be hostile, it's too much of a call for him."
