Promoter Frank Warren talks to Joe Calzaghe seconds before his super middleweight unification showdown with Jeff Lacy

WBO champion Calzaghe starts superbly and has his highly-rated American opponent on the back foot with his speed

By the end of the fifth round, Lacy's face is a mess - but the IBF and IBO title-holder's power remains a big threat

Many experts felt Lacy would impose himself as the fight went on, but Calzaghe shows no sign of relenting

And in the final round, Lacy is floored for the first time in his career and is almost stopped by the brilliant Welshman

Calzaghe, in what is regarded as his defining fight, wins by a landslide on points to take Lacy's belts

The win establishes Calzaghe as the top super middleweight and one of the best pound-for-pound fighters in the world
