Sweden won this game overcoming some poor football by 2 goals. The greeks started the game with a very defensive posture, 5-4-1. This made it extremely difficult for Sweden to penetrate, and it showed for a while. However, Zlatan got a bit of space late in the 2nd half, and fired the game winner in from about 20yards out. An excellent strike.
Greece had plenty of chances as well, had they put away some of them, they would have shown why they were the champions.
Playing in a 5-4-1 relies heavily on needing a goal early, and then defending strongly, or trying to pip a goal in the later stages (as they did in 2004).
