Whether this affair becomes an insurmountable burden affecting Madrid's Olympic bid remains to be seen El Pais Thursday press reaction

But in marked contrast, the issue is all over Friday's papers.

And rather than look ahead to this weekend's Real Madrid-Barcelona clash (traditionally one of the games of the Spanish season), the papers' focus is on events stemming from Wednesday's controversial match.

The biggest-selling paper in Spain devotes its first five pages to the racism controversy - "Football must not tolerate any more of these racist gestures" is its front-page headline.

"The game between Real Madrid and Barcelona is the right time to show to the world that we are not racist."

The paper uses a photo montage with Barcelona and Cameroon international Samuel Eto'o's face in white and Real Madrid and France midfielder Zinedane Zidane's face in black.

The accompanying headline reads: "Nothing would change if Samuel Eto'o were white and Zidane were black."

In its editorial, the paper asks: "Are we really racist? If we're not, why did so many of us stand idly by while people were making monkey chants towards black England players?"

Its editorial deplores the lack of leadership and sensitivity of the Spanish FA and Spain coach Luis Aragones.

It calls for Aragones to apologise immediately and stop trying to blame some kind of English press conspiracy.

The paper adds: "Whether this affair becomes an insurmountable burden affecting Madrid's Olympic bid remains to be seen."

It also carries a letter from a Spaniard living in the north-east of England who said that when he watched the game, he was ashamed to be Spanish.

Columnist Alfredo Relano says that while Aragones has not helped himself, the Spanish FA was more to blame for not providing its coach with better advice and support - "He is a football coach, only that."

And he adds: "Madrid's 2012 bid is wobbling."
