it's the meaningless games that are the most enjoyable - not least when they turn out to be far from meaningless because teams turn out to be adventurous. Remember Nigeria 1994, the attacking play of Japan and South Korea in 2002, and Ivory Coast v. Holland in 2006. The Scots still get pleasure from the victory against Holland in 1978
This year I'm looking forward to Serbia v. Ghana, any game you like in Group E, Paraguay v. Slovakia, Ivory Coast v. Portugal (which will doubtless be enlivened by Christiano Ronaldo complaining every time his mascara runs), and Switzerland v. Chile.
