Harrison (left) and Cook started exchanging insults as soon as their fight was announced

A bad-tempered conference call reached boiling point on Monday as Cook claimed he would easily claim Harrison's crown.

Cook said: "You've had your day and you're just another fighter for me, so you can just shut your noise."

But furious champion Harrison hit back, insisting: "I've seen your likes before pal, and I'll ****** shut your noise!"

Harrison's build-up to the fight has been far from ideal.

You're just a typical big mouth and you don't bother me at all Scott Harrison to Nicky Cook

Wthin days of arriving in his training camp in Malaga in October, the 29-year-old was arrested over allegations of assault and theft and spent five weeks in a Spanish prison.

And now Cook insists he is ready to add to the Glaswegian's problems by dethroning him at London's Excel Arena.

Cook said: "Scott's been a good world champion, he's been there and done it, but now there is a new kid on the block and I'm ready to take over."

He taunted Harrison: "I'm the one who's calm and collected and you are the one who's sitting there nervous - I've got you rattled."

But the champion retorted: "You're just a typical big mouth and you don't bother me at all.

"I'll shove that phone up your ****. I'll see you on 9 December."

Dagenham fighter Cook had the last word, however.

The unbeaten former British, European and Commonwealth champion, unbeaten in 26 professional fights, teased the champion, adding: "Yeah, I hope I see you too.

"Just make sure you turn up!"

The two fighters are set to meet at a press conference in London on Thursday, while the fireworks could continue at Friday's weigh-in.
