Cant blame them for being pissed off. Is a joke the amount of favouritism Madrid and Barca get in Spain.
Delusional to say the least.
Real Madrid and Barcelona get reported that much because they generate
the interest themselves. Lots of television and radio stations, sports newspapers and their journalists subsist alone because of these two clubs. Sponsors will choose to release their spots in shows related to them because they will get the bigger audiences and hence the bigger chance their product will be bought.
Forget how the interest is shared in England. In Spain it's all about Real Madrid and then Barcelona, with Atletico being third but still very far from these two.
