Carl Froch has expressed strong views on the events that have led to the fight between David Haye and Dereck Chisora.

Froch is disappointed in both men for different reasons and insists that he doesn't hype fights in the same manner.

He told the Evening Standard: "I don't know whether Chisora is mentally ill or unstable, but the way he was behaving in the build-up to the fight was totally unreasonable.

"It was disgraceful. He slapped Klitschko at the weigh-in and then spat in Wladimir's face in the ring. That is no way to behave. As a professional you should be leading by example."

Froch also admitted he is annoyed that Haye has come out of retirement for the Upton Park showdown.

"It winds me up," Froch says. "When people retire, they should stay retired. I was in Jamaica with David for two weeks after he said he was retired. He's made his money."

Froch will be an interested onlooker when Haye meets Chisora at Upton Park on Saturday night.
