Barcelona convincingly beat Real Madrid 3-1 in Saudi Arabia on Sunday to win the Spanish Super Cup, their first trophy since coach Xavi Hernandez took over.
Inspired by teenager Gavi, who scored himself and set up goals for Robert Lewandowski and Pedri Gonzalez, the Catalans produced one of their best performances in years against their bitter Clasico rivals.
Karim Benzema netted a late consolation for Madrid, who have been far from their best since the World Cup break and also fell three points behind Barcelona in La Liga last weekend.
Madrid coach Carlo Ancelotti suffered his first defeat in a final since 2014, with Los Blancos surrendering the trophy they earned last season to Barcelona, who have now won the Super Cup a record 14 times.
Xavi crucially deployed four central midfielders, with 18-year-old Gavi drifting inside off a nominal starting position on the left and frequently giving Madrid right-back Dani Carvajal the slip.
