Junior Witter has reacted to the latest speculation of a Ricky Hatton mega-fight by demanding: Put up or shut up.

Rumours of a much-hyped battle of Britain have resurfaced after comments from the Hitman's trainer Billy Graham.

He insisted that Hatton, who last week claimed the WBA welterweight belt, has "unfinished business" with the Bradford fighter.

"I know Ricky will give him the chance," said Graham in the build-up to Hatton's paper-thin points win over Luis Collazo in Boston. "Ricky really wants to beat up Junior Witter. It's personal."

It is a familiar old tale for British fight fans who have been waiting for years to see the biggest domestic dust-up get off the ground.

But Graham's comments are the strongest indication yet that Hatton would take the fight providing Witter claims the WBC world light-welter title this summer.

A grudge match between two genuine world champions might have the clout to interest American sports channel HBO, who have signed up Hatton for his next two fights after Collazo.

With Hatton dropping back down to the 140lb division, his natural fighting weight, the clamour for a lucrative clash with Witter is growing again.

Witter is tired of the constant references to Hatton. But he knows that a win over American DeMarcus Corley to become WBC world champion would be a genuinely powerful bargaining chip.

He told the Telegraph & Argus: "Hatton is always saying that if I win a world title then he would fight me. We'll see if he backs that up when I beat Corley.

"I intend to become world champion and then we'll find out if it's just words. I will put the feelers out but we'll have to see how it goes I'm not thinking about it at the moment.

"I didn't see the Hatton fight last week but from speaking to people whose opinions I respect, he didn't deserve it. I knew the weight would be too tough for him and, if it went to points, I thought there was a good chance he could lose."

Witter is expected to be given home advantage for his showdown with Corley, which is likely to take place in July.

The European and Common-wealth champion, out of the ring since October, said: "It's been annoying to have gone so long without a fight but everything is geared to peaking at the right time. Corley will find himself up against a fighting machine.

"I've been knocking on the door for a long time and now that I've cracked it open, people know I'm here and when I knock that door down they'll realise I'm a true world champion."
