Barcelona new boy Jordi Alba has been a genuine threat in Spain's formation this summer.
He solves the glaring hole revealed in the 2010 FIFA World Cup, where Joan Capdevila failed to impress, and effectively provides much-needed width to Spain's possession-hungry setup.
He's been tidy on the ball and a far more trustworthy outlet than Alvaro Arbeloa has been on the right side of defence.
Spain's packed midfield threatens to become unorganised and narrow at times, but Alba pushing on down the left allows the players in the middle of the park to retain their shape in relation to him.
Such is his dangerous reputation that Laurent Blanc fielded two right-backs to double-cover him in France's quarterfinal with Vicente del Bosque's side.
His goal in the final was sublime.
