Audley Harrison revived his reputation as a world heavyweight title contender when he battered fellow Briton Danny Williams into a third-round defeat in their hastily-arranged non-title revenge fight on Saturday.

Harrison, pilloried as "Fraudley" after his hopeless display when losing on points to Williams at the same ExCel Centre docklands venue a year ago, looked more like the crisp puncher who won Olympic super-heavyweight gold six years ago.

In the most impressive display of his laboured 22-fight professional career he left Williams bleeding with a sharp left inside the first minute and barely let up from then on.

With the world heavyweight scene desperately short on quality, Harrison is now backing himself to go all the way.

"My goal is to be heavyweight champion and hopefully the country will get behind me. In 2007 I will win the world title, in 2008 I will be undisputed," he said.

Williams, 33, suffered a broken nose and needed a mass of stitches to cuts on his nose and left eye and said he had probably taken enough punishment in his career: "Maybe it might be time to say goodbye," he said.
