World title challenger Paul McCloskey has vowed to keep his day job managing a local shop even if he dethrones superstar Amir Khan tonight.

The unbeaten Northern Irishman, 31, has taken time off from working alongside his wife at a mini-mart in his native Dungiven to focus on the biggest night of his life as he faces WBA light-welterweight champion Khan in Manchester.

The build-up to the MEN Arena contest has been dominated by Bolton star Khan and his television troubles this week, while European champion McCloskey (22-0, 12) has been somewhat overlooked.

Though he will not be overawed on his big night, he admits sitting next to Khan's superstar promoter Oscar De La Hoya at a press conference is a million miles away from his day job working in a shop.

"I won't change my life for anything and when I win this title I'll still work and manage the shop," he told Press Association Sport.

"If you said to me five years ago I'd be sitting in front of an audience with Oscar De La Hoya getting ready for a world title fight... it's surreal, it's nice."

McCloskey admits he has taken training to the next level ahead of his world title chance.

"I've moved from home, I've stayed away, I've brought a conditioner on board and I've a chef making all my meals," he revealed.

"Up until then, in my previous fights, I stayed at home and used to work five days a week with my wife, where we run a supermarket. So I've done a 360 degree turn with my camp to ensure I win this fight and we'll see it on Saturday night."

Khan, meanwhile, has fended more questions about television issues and future fights than he has about his challenger.

The Englishman's first fight on home soil since 2009 has been overshadowed by a falling out concerning the broadcast of the bout this week, with Khan insisting he receives more support from television companies in the United States than he does here.

After facing McCloskey he hopes for the chance to face American Timothy Bradley in a unification contest this summer.

But the 24-year-old told Press Association Sport that fights of that magnitude will have to be staged in America, especially in light of recent events which culminated in tonight's bout being screened on the obscure Primetime TV channel.

"I've always said from day one that there is more money to be made for me in America if I fought there, but I chose to come here and fight live in front of my own fans," he said.

"That's just me. I just wanted to do that and put a fight on.

"But being a British fighter and having more support from American TV just shows that as a British fighter I should have had British TV supporting me more.

"I'm not going to say it could be my last fight in Britain because I think there are some big fights for me in Britain.

"But I think it will be a long time until I come back again because while I want to have the big fights in England, it will be quite difficult to make them.

"I think they will probably be more likely in America."
