AMIR Khan must turn on the style if he is to realise his dream of winning a world lightweight title before the end of the year, according to his promoter Frank Warren.

Khan's 17th professional fight against Martin Kristjansen has been billed as an eliminator for a shot at new WBO champion Nate Campbell.

But Warren insists Khan must first prove he is fully ready for such an ambitious step up by looking good against the Dane, who has put his WBO inter-continental title up for grabs.

Warren said: "Amir is a quality fighter and if he is going places the Martin Kristjansens of this world are the kind of opponents he has got to deal with. And he has got to deal with them in style."
