Danny Williams is ready to emulate Lennox Lewis and become the dominant force in the world heavyweight division.

That is the opinion of the man who masterminded Williams' stunning fourth-round knockout of Mike Tyson in Louisville on Friday night.

Williams' trainer Jim McDonnell believes his charge has now gained the self-belief to go with the talent which always lurked inside.

McDonnell insisted: ''I think Danny has the capability to rule the heavyweight division.

''There are not many good champions out there now and in beating Tyson, Danny has gone to another level.

''I honestly think that with his mental status sorted out he will be unbeatable.

''He is 31 years old so he is still young in heavyweight terms. Danny can rule for years to come.''

Former European champion McDonnell got back with Williams this year following a separation.

And his rigorous training regime paid off handsomely for a fighter who many thought did not have the bottle to succeed.

Now Williams is looking up to the champions and was delayed in the United States for a round of television interviews.

McDonnell insists he is not immediately interested in taking up yesterday's challenge from the Olympic champion Audley Harrison.

McDonnell added: ''Fighting Audley now would be like coming out of the Premiership and going into the Second Division.

''Danny has got to look to the top, to the Vitali Klitschkos and Chris Byrds of this world. He is a major player now.

''Financially and physically Audley is no longer a challenge.

"He always accused Danny of using his name for publicity. That is exactly what Audley is doing now.''
