heres a low quality video 5th and 7th round
YouTube - Amir Khan Stops Kristjansen In Seven at Bolton Arena 2008
in the interview after the fight Amir's promoter Frank Warren said he would like to see Amir fight in the summer and then fight Nate Campbell for the world title before the end of the year
IMO theyve been putting him against fighters they knew he could beat, hes only went 12 rounds once and hes knocked 12 of the 17 fighters out in under 3 rounds
