Yes, Spain are boring. That was my answer, and I stand by it.
But boring here has a deep meaning. It's more entertaining than what England plays at, but considering the squad, their games at both World Cup and Euro Cup under Del Bosque have been quite boring. Except for the final game that is, and games here and there. In fact, I think criticism they got for the Euro games and the accusations they received forced them in a way to be more attacking in the final game. They have been asked 100s of questions about them being boring, they read Spanish media, which declared them boring as well. So I think they have been forced to be more attacking. And look what we have in hands, absolutely dismantled Italy. They are just that much better than Italy, and others.
Put it this way, not a single Italian player would get into Spanish 11. Not one. And why did first game finish 1-1? Not one single Croatian played get into Spanish team, why was it a cagey, cautious game with a 1-0 win at the end? Look back to World Cup, when Spain were similarly cautious vs the likes of Honduras, Chile and Paraguay.
It's all Del Bosque's cautious tactics. 2 defensive midfields is a must for him after that Swiss 1-0 win. He is more concerned about not conceding, and he is even ready to accept 50/50 penalties, like in Portugal game where he wouldn't change 4-6-0 formation up until penalties. That's what he is. There were loads of times when Navas etc. had brilliant opportunity for a fast counter or a cross into the box, but there was nobody there, so he had to pass back. Not only Del Bosque is playing 2 defensive midfielders, but he also is not encouraging going up forward into the penalty area. His idea is clear, strangle the opposition without the ball, and score 1 goal, and finish the game. He wouldn't mind more, but not at the expense of a risk. It does work, but it doesn't mean it cannot work otherwise.
Key here is the fact that Spain adopted Barca's possession football with Aragones. But Barca has some very important differences with Spain, especially since Del Bosque took over. Barca plays only one defensive midfielder, and are willing to take a risk against anyone, be it Real Madrid or Chelsea. Barca never pass around the ball after 1-0 for 70 minutes, they always go for 2nd, 3rd etc. When Barca attack, there are always 4-5 players in the box. Always. There may not be crosses, but penalty area is 99% of times crowded. The idea is to keep the ball to attack and score. But Del Bosque quite often wants Spain to keep the ball to waste time and defend.
So yes, Spain are boring. Much more boring than what they can show. I hate to see Spain doing absolutely nothing with the ball. But in a way, I can understand Del Bosque as well. He has won the world cup and euro cup with this attitude. When he tried to have a relaxed attacking Spain, Portugal and Argentina each scored 4 past Spain, and Italy won 2-1. Swiss won 1-0 as well. So he got his lessons for being too open and less controlling. I am sure he'd rather strangle teams 1-0 than try to get a 4-0 and get a 2-1 loss instead.
