1980s: Real Madrid dominate but the Basque Clubs disrupt their monopoly

Real Madrid's monopoly in La Liga was interrupted significantly in the 1980s. Although Real Madrid won another five consecutive La Liga titles (1986 to 1990) under the brilliance of Emilio Butragueño and Hugo Sánchez, the Basque clubs of Real Sociedad and Athletic Bilbao also dominated the 1980s. Real Sociedad won their first La Liga titles in 1981 and 1982; Luis Arconada, Roberto López Ufarte and Txiki Begiristain stood out from this team. Later, Athletic Bilbao also managed to win two consecutive La Liga titles in 1983 and 1984, also achieving their fifth La Liga and Copa del Rey double in 1984; The stars Andoni Zubizarreta, Santi Urkiaga, Andoni Goikoetxea, Dani, Manuel Sarabia and Estanislao Argote made this success possible. For its part, Barcelona won their tenth La Liga title in 1985 under coach Terry Venables, their first La Liga win since 1974.
