terms, based on evidence gained after police examined the messages sent by mobile phone between the gang members on the day. There have been a number of accidents and disasters in the history of football. Some of these, such as the Hillsborough and Ibrox disasters, were due to problems with crowd control. The Heysel Stadium disaster was a combination of hooliganism and poor crowd control. The Bradford City stadium fire was due to poor fire safety in the stadium. Lessons learned from these disasters have led to safer football stadiums and gradual bans on smoking. Matchday programme Matchday programme are sold inside and outside stadiums before, and sometimes during, matches. In their most simple form, they provide basic information on the teams, players, and match officials. Larger clubs usually produce multiple-page programmes with features such as comments from the manager and club captain, interviews with players, ex-players and backroom staff, information about ticketing arrangements for forthcoming matches, a detailed fixture list and review of the team's season so far, competitions, pages for junior fans, and a detailed feature on the opposition.

Another example is the 1977 British Home Championship match between England and Scotland, again at Wembley. After Scotland won 2–1, the "Tartan Army" invaded the pitch and managed to break down the goalposts, as well as cutting up the turf to take.

This commonly occurs after a team wins a championship, survives relegation or achieves an upset, typically in a cup competition. Solo invasions are more common although few in number. In some cases, these are streakers who try to invade the pitch while nude. Supporters tend to view this as harmless fun. One such pitch invasion was at UEFA Euro 2004, in the final
