In August 1974, a Blackpool fan was stabbed to death at the back of the Spion Kop, Bloomfield Road at Blackpool's home match with Bolton Wanderers. It was widely reported as being the first hooligan death at an English football match, and other clubs who gained notorious reputations for hooliganism during the 1970s and 1980s included Chelsea, Millwall, West Ham United, and Leeds United. The nadir came in May 1985, when Liverpool fans hooliganism, combined with poor policing and infrastructure, led to the deaths of 39 Juventus fans before the European Cup final, in the Heysel Stadium disaster. The sequel to the tragedy was a ban on English clubs in European competitions, which was not lifted for five years. Due to the ban, many English star players transferred to continental clubs. England's ageing and poorly built stadiums were responsible for two disasters, at Bradford in May 1985 (just before the Heysel tragedy) and Hillsborough in April 1989, resulting in the deaths of 56 and 96 people respectively.
