Why would you do that? They play the second most boring football on the planet after Greece. Pass-pass-wait. Pass-pass-pass-wait. Back the other way. Pass-pass-wait. Pass-Pass-roll on the floor like you have had your leg cut off. Also Torres is useless, Villa is broken, Pedro is broken, Raul is 74 years old, and they haven't really got a huge number of players to fill in up front. Puyol is also broken.
Well, I just happen to be their fan, and I enjoy their fluid style of play, which involves dominating possession through consecutive passings. This, I think, strengthens their defence simply by preventing their opponents from ever touching the ball and thus making any advances. The repeated passings can also help them penetrate the enemy lines. In a way, it's like playing monkey-in-the-middle with your opponent (him being the monkey, of course), and the match between Spain and Germany in the last World Cup showed this quite clearly. Anyway, I think Tiki-Taka is beautiful football, and it's fun to watch the Spanish playing in their opponents' half for the majority of the match.
Though, I haven't watched football in a while (what I said is simply based on the games that I've watched in the last Euro and World Cup), so I don't know if they have changed some of their strategies. I'm sure you know more about them than I do.
EDIT: just wanted add a few more things.
