Liverpool won a treble of trophies during Fagan's first season as manager, winning the League championship for the third year in succession, the Football League Cup for the fourth year in succession and a fourth European Cup. The following season, the club was involved in one of the worst disasters to occur at a football stadium. Before the start of the 1985 European Cup Final against Juventus, Liverpool fans breached a fence separating the two groups of supporters, and charged the Juventus fans. The resulting weight of people caused a retaining wall to collapse, killing 39 fans, mostly Italians. The incident became known as the Heysel Stadium disaster and resulted in the expulsion of English clubs from European competition for five years.
