Junior Witter's trainer reckons it is win or bust for the Bradford fighter in his world title showdown.

Dominic Ingle admits the stakes could not be any higher as Witter prepares to face DeMarcus Corley for the WBC light-welterweight crown in London a week tomorrow.

"Junior has got to win, otherwise he's back to square one - and possibly even below that," said Ingle.

"He could go back to European level and scratching around there but his chance would have gone.

"There are so many big fights in the pipeline but it's all down to Junior. He knows what could be in front of him but he has to beat Corley."

Top of that dream list would be a long overdue battle of Britain with Ricky Hatton - "the biggest thing in British boxing since Benn and Eubank", according to his trainer.

Ingle said: "Hatton keeps trotting out the excuse that American TV wouldn't want it but they would do if the WBC title was on the line. But Junior knows that won't happen unless he wins next week."

Witter has been put through a punishing training schedule, with three gym sessions a day as well as hill and road runs, and Ingle detects a more focused and determined fighter than before his ragged wins over Andreas Kotelnik and Colin Lynes.

Ingle said: "Junior is in a different type of mode. It's the same as when he fought Lovemore N'Dou and knew he would be up against it.

"Fighters like Junior are at their best with their backs against the wall. He needs challenges and this is the pinnacle.

"We know Corley can punch but he is also prone to taking a shot and going down. He's a bully and you've got to fight fire with fire and get on top of him.

"But I think N'Dou was a tougher proposition. He'd never been knocked down - Miguel Cotto didn't put a dint in his armour - and Junior put him down twice."
