Great Britain's performance director seeks Taekwondo World Championship success
GB Taekwondo's performance director Gary Hall outlines the importance of success for his fighters at the World Championships, which got under way with a spectacular opening ceremony in Gyeongju, South Korea.
BBC Sport's Nick Hope was there and also caught up with Great Britain's European champion Aaron Cook ahead of GB's first fights on Monday 2 May.
Success at the tournament is vital for any fighters hoping to qualify for the 2012 Olympics as British Taekwondo must name the four weight categories (two male and two female) that they are nominating for the London Games by the end of May.
