Junior Witter is being lined up for a money-spinning showdown with two-weight world champion Diego Corrales.

Talks have begun in America to match Bradford's WBC light-welterweight king with one of the most exciting fighters on the scene.

Witter defends his title against Mexican outsider Arturo Morua in London on Saturday but the net is already being cast wide for future big-name opponents - and Corrales is well up the list.

Corrales has been crowned at both super-feather and lightweight but was forced to give up his own WBC belt after weighing in at four pounds over the limit for his last defence against Joel Casa-mayor in October.

Now he wants to join that rare breed of world champion which has conquered three weight divisions - raising the possibility of a mouth-watering clash with Witter.

"There is a lot of interest for that fight," confirmed Witter's promoter Mick Hen-nessy, who hopes to get him on an HBO show in the States in April or May. "Whatever some people might think, they are very interested in Junior in America.

"Corrales is one of the biggest names in US boxing and if we can manoeuvre it for Junior, what an incredible fight that would be.

"Golden Boy Promotions have been working on that fight a lot and we want it really badly. And we all think that Junior Witter will do a job on Corrales."

The 29-year-old Corrales has won 40 of his 44 fights, with 33 knock-outs, and shot to fame after some fierce battles with Casamayor and Jose Luis Castillo.

Castillo fights in a WBC eliminator next month against Herman Ngoudjo but has made it clear he is more interested in facing Ricky Hatton than title-holder Witter if he wins.

Witter's trainer Dominic Ingle believes the likes of Corrales and Castillo are not the invincible warriors that some claim.

Ingle said: "America has put these guys on a pedestal but they aren't as good as they make them out to be. But they are big box office and those are the fights we want. Hatton is still playing cat and mouse but we want Junior recognised in America. We thought that would happen when he beat Lovemore N'Dou but there has been a bit of a lull.

"Junior is still growing into the title and you're going to see the best of him in these next few fights. The harder the opponent, the better he will look."

Witter is desperate to crack the lucrative US scene in 2007 and said: "Bring me the names America are talking about and I'll beat them up. I want to be big over there."
