The World Cup
This summer's World Cup competition will see teams competing to play the world's best football. But the football they play will not all be of the same kind. The fans expect different styles of play from Brazil, Germany, or Italy.
What makes Brazilian football Brazilian? Our style. of playing football contrasts with the Europeans because of a combination of qualities of surprise, accuracy and good judgment. This style. has won Brazil five world cups. Yet many Brazilian fans only count four of these victories. In 1994, the team abandoned this style. for modern, scientific training and tactics. The team won the cup, but in a boring way.
The Italians think differently.” To many Italians, the score 0-0 has a glorious quality, suggesting perfection,” says the British football writer Simon Kuper. In the Italian culture, the idea of face is very important. This is why Italian teams are traditionally built around strong defenses. The Dutch footballer Johan Cruyff once said that Italian teams never exactly beat you. It's just that you often lose to them.
In Holland, there is a tradition of decision making through argument and discussion. It is a society where everybody is expected to have a point of view.” Every Dutch player wants to control the game,” says Arnold Muhren. “You play football with your brains and not your feet.”
“A Dutch player argues,” says Simon Kuper. “An English player obeys his superior. He is a soldier.” The qualities valued in English football are military-strength, aggression and courage. This can make for exciting football. But it also means that the English find it difficult to use skillful players. David Beckham is usually criticized for his failure to defend-despite the fact that he is an attacker.
If the English like to fight, the Germans like to win. In recent years, Germany has tried to change its image as a country of ruthless efficiency and a desire for victory at all costs. But Germans are quite happy for these qualities to remain in their national football team.” Football is a simple game,” Gary Lineker once said.” You kick a ball about for ninety minutes and in the end the Germans win.”
It's difficult to predict who will win this year's World Cup. There is no strong favorite. But a look at the track record of previous winners shows that it is the nations with the strongest national characteristics in the football that perform. best. It seems that you need to know where you come from if you want to get to the top.

D. Ruthless efficiency.
What is one expected to do in Holland?
