Millwall's unwanted association with football hooliganism became strongly apparent with their rise in the English game during the 1980s. Millwall's Bushwackers were already one of the most notorious hooligan firms in the country by 1985, while Luton Town had their own fringe of hooligans in the MIGs. The Den, home of Millwall, had been the scene of a riot seven years earlier, when during another FA Cup sixth-round match against Ipswich Town Millwall-aligned hooligans had injured dozens of their own club's supporters. Following the incident, the opinion of Ipswich manager Bobby Robson was that "[the police] should have turned the flamethrowers on them".
