European success first came for the club in 1977, when they won the UEFA Cup. Although relatively luke warm on the European stage at this point; they had won the Italian championship five more times throughout the 1970s.
Franco Causio became a very popular player at the club during the 1970s, in fact he was so popular that the club allowed him to wear his hair long, prior to Causio this was against the rules. The club also provided the team with official formal wear (made by famous tailors) and forced them to complete their educational studies. Most of its players remained with Juventus until the end of their careers; many still work for the club or for Fiat (or related companies).
The height of European success was not reached until 1985, when they won the European Champions Cup, but this success was largely overshadowed by the Heysel Stadium disaster that had occurred during the final between Juventus and Liverpool, in which 39 people were killed.
