Amir Khan v Kell Brook: Brook promises 'drama' and vows to expose rival's chin

Kell Brook believes Amir Khan's greatest weakness is his chin and is ready to expose his British rival in their fight on Saturday.

Brook and Khan finally step into the ring together after a near 20-year feud and will fight in Manchester in a contest at 10st 9lbs (68kg).

«Timing beats speed,» he added. «I always find a way to get my shots off.

»We're in there for a long time — there will come a time when we exchange. There is going to be a lot of drama in the fight."

Khan dismissed Brook's assessment of his chin and insisted he has seen the desire drain out of his opponent in recent years.

The Manchester Arena sold out in just minutes with fans desperate to see the two British fighters finally face off in the ring despite both men now being past their prime.

«I don't like his attitude, his lies,» Brook said of Khan and their long-standing rivalry.

«I think the boxing world knows I always wanted this fight. When he says
