Spanish players would be in line to receive a huge bonus if they manage to defend their World Cup title in Brazil.
National team captain and vice-captain Casillas and Xavi have agreed on their World Cup bonuses with Jorge Pérez, the secretary general of the Spanish Football Association (RFEF).
Players and technical staff would receive a sum of €720,000 ($979,000) if they manage to defend their World Cup title in Brazil: 20% more than they received in South Africa and more than double what the Brazilians or Germans would get.
The host nation would receive €330,000 ($448,000) while the Germans players would receive €300,000 ($408,000) if they lift the trophy.
"Spain will pay more than double the Bonus that Germany will for the Football World cup. Are we twice as rich as Germany?" a Spanish politician wrote on Twitter.
"We see it as an investment. We share what FIFA pays us with the players", the RFEF explained to 'El Pais' newspaper.
The winner of the World Cup will be awarded €27 million ($37 million) by FIFA which is 37% more than was awarded in South Africa.
Manchester United play-maker Juan Mata does not want the bonuses to be a distraction and wants to stay motivated to try and defend their title.
"Sometimes this subject is used against us, but I play with the same dream that I've had since I was a boy of winning the World Cup. I don't think about anything else. It's not within my control to decide whether it's made public or not", explained Mata.
