Kiko Casilla stopped from speaking Catalan by Real Madrid

Real Madrid seem to have a great deal of respect for languages like English and Portuguese, but none for Catalan. On Sunday we saw another demonstration of it. 

After Madrid's 3-2 win over Valencia, Kiko Casilla who started, spoke in the mixed zone. Among others, Catalunya Radio asked him a question in Catalan. Casilla asked to respond in Catalan, but the press officer present stopped him and told him he had to respond in Spanish. 

The posture of Real Madrid is surprising, because they never stop players like Bale talking in English, Ronaldo in Portuguese, Modric in Croatian, etc, but it seems that Catalan is being treated differently. 

You would have to suppose, then, that journalists in Madrid can speak English, Portuguese, Croatian... but not Catalan.
