There is something intriguing about legendary fights when one professional claims to have schooled the other.
That definitely adds a different aura to the game. Any game that Amir Khan is involved in cannot be anything but low key and when he claims that he schooled Kell Brook, his opponent in the upcoming fight that makes the event even more unique. Latest news states that Amir has claimed that he schooled Kell Brook before he started to fight as a professional. He trained him in sparring styles.
The training occurred before Kell became a world champion. The training took place before 2004 Olympics that was held in Athens. Amir and Kell trained in sparring styles as part of the Olympic camp for the events in 2004. Khan trained as an IBF welterweight champion in that period as well.
