Urango beat current two-weight world champion Miguel Cotto as an amateur

The 26-year-old Colombian insists he is no mood to concede his crown as Hatton bids to regain the belt he relinquished last year after moving up a weight.

Urango said: "Ricky Hatton has not fought anybody with my strength before.

"I intend to show I am the best in the 140lbs division. I do not believe there is anybody better at this weight."

Urango, who has won 13 of his 17 professional fights inside the distance, took his chance to claim Hatton's old title via a disputed points win over Naoufel Ben Rabah last June.

He added: "I have watched Ricky's fight with Kostya Tszyu several times, but he is not fighting Tszyu on Saturday, he is fighting Juan Urango.

I've got a lot to prove because of the criticism over my weight and moving back down a division Ricky Hatton

"You only have to look at our styles to know that it will be a head-on contest. I think the fans are going to see something great because the styles will make a great fight."

Meanwhile, Hatton admits he has a point to prove after piling on the pounds in the wake of his only fight last year, in which he claimed the WBA welterweight belt by out-pointing Luis Collazo.

But training in Wayne McCullough's Las Vegas gym this week, the 28-year-old Manchester puncher looked in sensational shape, indicating he was giving plenty of respect to underdog Urango.

"I've got a lot to prove in this fight because of the criticism over my weight and moving back down a division," Hatton said.

"My inspiration is people saying I'm too fat. I want to win this and be able to say to my critics 'now, what do you think of that?'

"I cannot go crazy out there, although I am determined to get back on track performance-wise and send out a message.

"It is going to be a dangerous fight but I believe I can do just that on Saturday night.

"A lot of good British boxers have lost in Vegas before, but I will make sure the occasion does not get to me.

"In Boston against Collazo, which was my first fight in America as top of the bill, I tried too hard to put a show on and I need to make sure that doesn't happen in Vegas."
