Related documents: [0]  [DOC] The Football League Super Cup (later known under its sponsored name as the ScreenSport Super Cup) was a one-off football club competition held in England in the 1985–86 season. It was organised by the Football League and was intended as some form of financial and sporting compensation for the English clubs which had qualified for European competition in the previous season but had been banned from entering European tournaments by UEFA following the Heysel Stadium disaster. With the ban set to last into the foreseeable future, England's clubs stood to lose a great deal of revenue, and would also have fewer opportunities to win silverware, so the Super Cup was established in order to hopefully offset at least some of this lost income, as well as offering additional competition for them.
