Cristiano Ronaldo could face sanction for his controversial celebration that followed his 42nd goal of the season

Cristiano Ronaldo could face punishment for his celebration after scoring for Real Madrid in El Clasico on Sunday.

The ex-Manchester United forward appeared to urge Barcelona fans to calm down after making it 1-1.

Spanish league (LFP) president Javier Tebas says they will investigate as they are keen to clamp down on provocative actions.

The policy follows the death of a Deportivo La Coruna fan in fighting before a league match in November.

"We have to be careful with provocative gestures by a player or conduct that could incite violence among spectators," said Tebas.

"It must be sanctioned, from a fine up to a suspension. We will look into it."

Barcelona went on to win the match 2-1 with Luis Suarez scoring the winner.
