You don't have to play great football to become world champion either. There have been more countries in the past that didn't play great and still became champions. Just think of the boring final of 2010 in which Spain - the Netherlands did not get further than 0-0. Argentina may have had some luck with the referee, but the penalties it has had are all explicable. You even saw people selling their houses to be able to attend this tournament. A very big party in Argentina, nice to see. But now you will have to arrange another house.
