Barcelona fans went into the El Clasico being urged not to barrack Real Madrid star Cristiano Ronaldo.

Barca are already being investigated for the recent chants of "Cristiano, drunk" during their league meeting with Levante and were keen to see tonight's game pass without any similar incident.

Club representatives and the local police force 'Mossos de Esquadra' met with supporters' groups earlier this week to ask them to respect the rules and respect the rivals.

Barcelona also broadcast messages during the game urging fans to respect the players.
