Italy clearly has the easist path to the Semi's. They should cruise through, even with a upstart Swiss team in the way, Italy will handle them without much challenge.
Brazil vs Spain s& Germany vs Argentina should be some incredible matchs of the round of 8, if it plays out to form.
England or the Dutch should advance from thier bracket, I say this cause if the Dutch beat Port they should beat England, but if Port beats the Dutch I think the 3 Lions match up quite well w/ Port as long as the backline is fit to play.
