The Spanish giants cannot believe what has happened. It seems they were not aware that many teams have advanced in the way they play their football. This has been so disastrous for the Spanish national team.
1. Involving many players from Barcelona.
To me this is one of the reasons as to why La Roja has not managed to defend their championship. We have seen these Barca players since 2008 in the squad. The same players in Euro 2000. The same players in Euro 2012 and confederations cup in 2013 where Spain ended with a 3-0 defeat from Brazil.
2. Perfomance of Barcelona
Perfomance of Barcelona this season was not good enough and they did not get any trophy in the 2013-2014 season. They were defeated in the final by Real Madrid and lost the Copa del Rey. They were denied a chance to lift the spanish title by Atletico Madrid. They were also eliminated in the champions league by Atletico Madrid. Taking 7 players from this team is a risk.
3. The approach in the 1st game
In the 1st game against Holland, Spaain looked to play like Real madrid. It was a sandwich of Mdrid-Barcelona style. This approach made them so vulnerable especially in the second half of the game. They could play their famous formation of 4-6-0. To me this could give the dutch men a hard time.
