automatically relegated, while the fourth from bottom entered the play-offs. In the Second Division, the top two clubs gained automatic promotion, and the teams finishing in third to fifth competed in the play-offs. Chelsea had been Second Division champions in the 1983–84 season, and had played in the First Division for the four seasons since. After two sixth-placed finishes in their first two seasons in the top tier, they dropped to 14th in the 1986–87 season. Middlesbrough had a more turbulent recent history: they were relegated from the First Division in 1982, and four years later dropped down into the Third Division. They were also struggling financially, and in July 1986 their debts forced them into liquidation. The club were locked out of their Ayresome Park ground, and only a last minute rescue by a consortium saved the club. Middlesbrough gained promotion back to the Second Division at their first attempt in the 1986–87 season. According to accountancy firm Deloitte, the match was worth £1million to the promoted club through increases in matchday, commercial and broadcasting income. Football hooliganism Football hooliganism has been present within English football since its inception. In the 1960s it escalated and developed from attacks towards oppositions players into fights between opposing fans. The driving force behind the escalation was predominantly groups of young, male fans who wanted to prove their toughness. By the middle of the 1960s, football hooliganism was considered a national problem which affected the image of England overseas. Local and national government intervened to tackle the problem rather than leave it to the football authorities. Measures introduced to deal with hooliganism were the segregation of opposing fans at matches, which was initially voluntary, before later being enforced, and an increased police presence at football matches. Security fences were erected at grounds, often topped with barbed wire, to keep fans apart and off the pitch. Although this segregation resulted in reduced violence at football matches, it helped to foster a collective identity for the groups of supporters, and often just shifted the violence out of the stadium into the nearby streets. This in turn led to the creation of what Ramón Spaaij describes as "super hooligan" groups, such as Chelsea's Headhunters group, who actively sought out fights against opposing fans. In 1985, a series of incidents brought English football hooliganism to a head. First, during a match between Luton Town and Millwall in
