The Spanish Football Federation (RFEF) has decided to investigate Barcelona striker Samuel Eto'o's insulting comments against Real Madrid during Sunday's title celebrations.
The 24-year-old Cameroon international chanted "Madrid, cabron, saluda al campeon" (Madrid, bastards, hail the champions) into the microphone during a speech at the Nou Camp.
Eto'o held a news conference on Monday to apologise, saying: "I never wanted to show any lack of respect to anyone. What happened was that in a moment of joy I started to sing and that was all. I beg forgiveness and hope that people will understand me."
Barca won their first league title in six years last Saturday, while Real Madrid, Eto'o's former club, finished second.
