There are two competing movements in football. On the one hand, there is tactical evolution, which for almost half a century has been increasingly moving in the direction of greater cohesiveness and team play, prioritising the structure and the system beyond all else. And on the other, there is the cult of the individual, the star player who seems so attractive to the mega-investors who are taking over the game at a top European level.
Occasionally the two coincide—as at Barcelona or Bayern Munich—but for many, including for instance, Arrigo Sacchi, the focus on individuality is stifling tactical innovation.
At club level, certainly in the Champions League, system tends to win—Bayern Munich, Barcelona, Borussia Dortmund and Chelsea were all sides that prioritised system, while Real Madrid, with their band of brilliant but disparate talents, have so far found the semi-final the limit. Paris Saint-Germain may face the same problem.
But at international level, the game is rather different. Systems take time to develop, far more than the week or so six times a year that international managers are afforded. The three weeks coaches usually get before a tournament help—and Roy Hodgson has already said he is relishing the prospect of that time to do proper structural work with his team—but essentially national teams play far less systematised football than club sides.
If a national team draws the bulk of its players from one or two clubs—as is the case with Spain and Germany; if they've been together for a long time—as is the case with Chile and Uruguay; or if time can somehow be created for lengthy preparation—something South Korea benefited from in 2002, then that can help the process of systematisation but, generally speaking, individuals are more important at national level than they are at club level.
