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

FC Barcelona reportedly took home record gate receipts in El Clasico at the weekend when beating its bitter rival Real Madrid 4-3.

All three prior clasicos have been high scoring — at least for Barcelona with 12 total goals to Madrid's four, so expect more goals against the depleted defenses at the Olympic Stadium.
