Match Preview:

Spain: Santi Cazorla has returned from the dead. Álvaro Negredo gets a start up front. And Andrés Iniesta is still the best. I have a good feeling about this lineup. If only Bruno Soriano were in place of Sergio Busquets, but I quibble. Álvaro Arbeloa against Cristiano Ronaldo is the key matchup for the suddenly stalwart back four.

Portugal: Nani is useless. Helder Postiga is injured. Hugo Almeida is a threat in the air, but the Portuguese wings need to provide more service. And then there's Ronaldo. Can he outwit his four teammates and inspire Portugal to a famous victory? No better place than here, no better time than now, as Rage Against The Machine once said.
