Robert Lewandowski struck twice in three minutes as Barcelona crushed rivals Real Madrid 4-0 on Saturday, inflicting the Spanish champions' first La Liga defeat in over a year.
Teenage winger Lamine Yamal and Raphinha completed the rout, while Madrid superstar Kylian Mbappe had two goals ruled out for offside on a frustrating first Clasico appearance for Los Blancos, who now trail league leaders Barcelona by six points.
France captain Mbappe was consistently outwitted by the visitors' high defensive line to the chagrin of the exasperated Santiago Bernabeu crowd, whose mood darkened as Barcelona hit four second half goals.
Barcelona snapped Madrid's 42-match unbeaten streak in La Liga, one game short of the Catalan giants' all-time record, adding further shine to their triumph.
