On Sunday night, Barcelona beat Real Madrid 2-1 in a thrilling El Clasico fixture.

Although the victory has put the Catalans four points clear at the top of La Liga, Lionel Messi and co might regret not scoring more at the Nou Camp.

Barca lost 3-1 in the reverse fixture last year at the Santiago Bernabeu and if Real manage to draw level on points with them, they will snatch the title because of a superior head-to-head advantage.

Real famously pipped Barca to the title in the 2006/2007, despite scoring 12 goals less and conceding seven more.
