Ricky Hatton is out to cement his legacy in Las Vegas tonight.
The Hitman will be crowned pound-for-pound champion if he beats Manny Pacquiao at the MGM Grand in arguably the biggest fight of the year, live on Sky Box Office.
Victory will also cement Hatton's place in the Hall of Fame and confirm his standing as one of the very best boxers Britain has seen.
It will be the second time he has challenged for the right to be called the best in the world, having lost in the same ring as Floyd Mayweather Jr in Decmber 2007.
That 10th-round KO was at welterweight though and as he puts the finishing touches to his preparation for the light-welterweight clash with Pacquiao, Hatton is convinced it will be different. It's his weight, his time.
"I've won a world title at 147lbs but the two trips up to welterweight have not been the easiest," he told skysports.com.
"But at 140lbs no-one has come close to me, without sounding disrespectful to my opponents. Kostya Tszyu came nearest to shocking me really and he was a powerhouse of a man - and I made him quit on his stool.
"I think size will be a factor and I think the way I'm boxing right now, technically, will be too much for Manny Pacquiao. He's only had two fights above 130lbs - and one of those was against a weight-drained Oscar De La Hoya.
Bulldozed
"The way I'm boxing technically, the fights I've had with everybody at 10 stone, no disrespect to any of them, I've just bulldozed."
Hatton believes Pacquiao will be 'easy to hit' and is relishing the chance to exploit a rare size and weight advantage over the four-weight world champion.
He has promised to make that count provided referee Kenny Bayless lets him get in close, and fulfil a dream that refused to die after that Mayweather defeat.
"I am convinced," he said. "It's very rare for me to have a height advantage over anyone and it's only a small one, but I won't be reaching for my punches at all. I've got the height and reach advantage which I have rarely had over the years.
"There's a lot of people picking Manny Paquiao to win it, so as if defending your world title wasn't enough, as if beating the number one pound-for-pound fighter in the world wasn't enough, you're doing it when everyone expects you to get beat.
"It would be an absolutely massive achievement to win and be the best pound-for-pound fighter in the world."
