So Spain's striker situation is so shit that without Villa you are screwed? wow pathetic....
Not necessarily; it's just that (I am assuming) Del Bosque and the midfielders don't want to change the way they play from only short passes to adding more crosses (which would also require a change in the starting lineup - ie. actually playing with wingers).
Llorente is a striker who scores goals off crosses - this past season, he scored more goals with his head than with his feet. He isn't particularly fast, but he is tall (1.95m) and has quite a physical presence to win balls inside the box.
Personally, I would like to see Navas on the right and Llorente in the middle, but that requires Spain to play slightly differently which won't happen unfortunately.
...and we still have no idea why he chose Negredo over Soldado.
