Man charged with assault following attack on Sheffield Wednesday goalkeeper Chris Kirkland Cawley, from Cheltenham, Gloucestershire, is due to appear at Sheffield Magistrates' Court this morning. The incident was caught on camera by Sky Sports which was broadcasting the derby game. Meanwhile, Leeds chairman Ken Bates believes the fan who attacked Kirkland has caused severe damage to his club's efforts to improve their image. While Bates has been pleased with the reactions of most Leeds fans, he is upset the club have been tarnished by the actions of one person. "What is encouraging is that I am told the vast majority of Leeds fans were as appalled by what happened as everyone else," Bates told the Yorkshire Post. The idiot who ran on the pitch better not go anywhere near Elland Road again. There are a lot of people angered by what he did. We have been working hard as a club to improve our image over the past few years. But this guy has done so much damage to that. It isn't fair on the overwhelming majority of Leeds fans. It doesn't do any of us any good, especially at a time when we are working so hard to get this club where it deserves to be.
