Mike Tyson doesn't care much about what people think of Frank Bruno's chances in Saturday's heavyweight title fight.

Because Tyson doesn't give the British challenger any chance."It's no concern to me what people think about the outcome of the fight," Tyson said Wednesday. "I'm the best fighter in the world and I'll prove it again on Saturday."

Tyson was terse and to the point as he and Bruno appeared together at their final news conference before they meet for Tyson's undisputed heavyweight title.

"He's going to be in a lot of trouble Saturday," predicted Tyson.

Why, asked a reporter.

"Just believe me, he will be," the 22-year-old heavyweight champion replied.

The oddsmakers agree with Tyson, making the champion a prohibitive 71/2-1 favorite in man-to-man betting to retain his heavyweight titles. A bettor can get even-money on a wager of whether the fight will go more or less than four rounds.

But Bruno insisted again that he is catching Tyson at just the right time, when the champion is again beset by personal turmoil.

"I've said it from the beginning and I'll stick to it," Bruno said. "I think it is a peak time to beat Mike Tyson."

Asked what he could expect Saturday night, Bruno answered:

"A new heavyweight champion."
