when madrid always boycott the press conference because of frustrated

That's both a good and bad thing. Good thing in boycotting press conference is to not add further pressure on the players who didn't perform well enough. If Real madrid really thinks that the referee is biased, all the more they should talk to the press instead of hiding away. By hiding, all the more it shows, the team is not performing the way they should. The players knows it, and that's the reason why. If big teams are allowed to boycott when they are not playing well, all the more small teams should just boycott the match if they think they are going to lose, right?

Yeah if i am not mistaken Sir Alex boycotted journalists from BBC, right?sometimes journalists ask and tend to judge too much LOL. At that time Madrid got panic after two draws..but now Madrid is back to winning way..

Real Madrid is not the only club who does it. Man Utd and Ferguson is guilty of it as well. In fact, there is a period of time whereby Ferguson banned journalists from a certain newspaper. Sometimes, one should understand their reasons behind the boycott. After a game where there were injustice, temper will rise. As a result, they might have utter something during the press conference that will lead to suspension from the authorities.

I don't know. But i think it's better for Mou and Madrid crew not to give any comments. Because i think, whatever they say to the press, it will always look bad. Media know that if they could make Mou's statement a controversy, they would do it. As for Mou, he just couldn't hold anything he want to say. If he want to say his mind, than he would say it. So i think it's best for them right now, not to give any statement. Just like Juve do in a couple weeks ago with their silenzio stampa. Well, it's just my opinion ...
