There is quite a lot of criticism here regarding Negredo being left out. In the past Torres and David Villa would be untouchable, but Spanish supporters have begun to see them as on the downward slope and in need of replacement.
Costa is injured and may not be able to play the first few matches, and even when he does, he is not the right striker for our system. Torres is unfortunately a shadow of his former self and showed a real lack of sharpness last night (his attempted lob, when he could have simply placed it low either side of the keeper, ended up hitting a churro vender in the car park). David Villa still has the gift of holding up playing but no longer will beat any backs on the dribble and has trouble finishing off matches with energy.
I think Del Bosque was pushed into taking the biggest names for many reasons, not all of which were sporting-related. I think we'll go out in the Quarter-finals this year, which is disappointing but our reign couldn't last forever.
