If Italy are going to beat Germany they have to score first. If they don't score first they are going to be in trouble. I feel like at times Italy does everything but score, they need to put one in, preferably in the first half. Historically speaking Italy has a good history against Germany, however I think Germany has a better offense than they did in 2006, it's more explosive.
Ever since Portugal lost to Germany they have dominated every game they have played in, and Ronaldo is a man possessed scoring three times and hitting the post four times. Spain will dominate possession, however if Ronaldo's shots go in the net, and not off the post Spain could be in trouble. Honestly I think each semi final game is a coin flip.
