Gomez insists his story will end with win over Khan

Michael Gomez is hoping a shock victory over Amir Khan tomorrow night will provide a happy ending to the biopic being filmed about his colourful life.

Gomez is aiming to inflict a first professional defeat on 21-year-old Khan when he challenges him for his Commonwealth lightweight title in front of a sell-out crowd of 10,000 in Birmingham.

Should Gomez succeed, it would be one more extraordinary scene in story that began when he was born in a car that had been crashed by his partially-sighted father, an Irish traveller who had taken the wheel when Gomez's mother went into labour on the way to hospital.

After the family moved to Manchester, the young Gomez got into a series of scrapes that included being charged with murder following a street fight - he was later acquitted of a reduced charge of manslaughter - and 'dying' after a stabbing, only to have his heart restarted on an operating table.

His fight career hit the heights with a stoppage of the previously unbeaten Alex Arthur in 2003 but plummeted two years later when, in mid-fight, he dropped his gloves and turned his

back on opponent Peter McDonagh. Gomez, 31 tomorrow, caused controversy this week when he failed to appear at a head-to-head press conference with Khan, who said his rival was "an idiot" and "scared".
