Young forward Samu Aghehowa was in disbelief after missing out on a chance to play in his first World Cup with Spain because of a serious knee injury sustained while playing with Porto.

The 21-year-old Samu got hurt in Porto's 1-1 draw with Sporting Lisbon in the Portuguese league on Monday in what he called "the unluckiest day" of his career. Porto said he sustained a torn ACL on his right leg.
