After knocking Real Madrid out of the Copa del Rey, Barcelona now have the opportunity to send their rivals packing in the title race too.
Barca's 3-0 victory on Wednesday means Barca will return to the Santiago Bernabeu on Saturday with a spring in their step, even if Madrid were the better side and had the better opportunities until the chaotic final 30 minutes, when a Luis Suarez double and Raphael Varane own goal gave victory to the Catalans.
A repeat this weekend in La Liga would leave Santiago Solari's side 12 points adrift of Barcelona, who would effectively have an extra point's advantage given their superior head-to-head record.
They should feel confident if recent form between the two sides is any guide. The Copa del Rey win was Barcelona's fourth in six games at the Bernabeu.
