Watched this interview between the pair of them when Khan was at 140lb and Ricky Hatton was making a comeback.

They are arguing about their sparring session and who got the best of it. Khan said he "schooled" Brooks. Kell said no one has ever schooled him. Khan also said he would knock out Brooks.

Khan is a lot more respectable and PC about Kell Brooks but even then they said the fight would be on Sky PPV box office and Audley Harrison said it would fill a football stadium.
