Barcelona's 4-3 El Clasico win was overshadowed by controversial refereeing decisions, particularly the disallowed goal by Fermin Lopez.

The point gap between first and second place in La Liga's is just small enough to entertain the idea of Real Madrid getting the better of Barcelona on Sunday, a result that would send both teams into a frantic race to the finish line.

It was another brilliant El Clasico for the neutrals, and another one that Real Madrid legend Carlo Ancelotti will rue as the celebrated boss went 0-for-4 against Barcelona this season.
