Here's a fine answer from Simon Critchley writing in the New Republic.
Connoisseurs like to argue that football is an art form, and it’s true that the enjoyment it generates is fiercely aesthetic. As I’ve written elsewhere, for me, a product of the Irish-Anglo minestrone of Liverpool, football is working-class ballet. There is a great beauty in a deft move or sequence of plays. Sometimes this is the tiki-taka of Barcelona at its peak, the Barca players harrying the opposition into losing possession, then moving the ball relentlessly, then effortlessly tapping it home. Sometimes it’s the physical power and attacking speed of Bayern Munich as they demolished Barcelona 4-0 (then 3-0 for good measure) in the Champions League semifinal last year. As in art, one movement gives way to another. Part of the anticipation for this World Cup is which school will emerge ascendant.
But more essentially, the truly great players possess grace: an effortless containment in their bearing and elegance of movement, long periods of idling interrupted by sudden accelerations and pivots, bursts of controlled power. When a player does this alone, the effect is stirring; when four or five do this in concert—as with Brazil in 1970 and 1982, and Spain in 2010—it is breathtaking.
There’s another component to grace, however. It is the cultivation of a certain disposition, some call it faith, in the belief that grace in its physical form will be dispensed at the crucial moment. Found in the players who have to believe that their bodies will perform at the precise instant when they are called upon, it is what we call composure. Yet it also exists in fans, who may find it hard to be composed, who may in fact be red-faced and screaming their heads off, but who are nonetheless bound up in something larger by their belief that something graceful, magical, is about to happen on the pitch. One hears from skeptics that football is boring, but it is the inaction that allows for the sudden, sometimes absurd, ultimately vitalizing escalations of tempo and drama. You have to pay close and constant attention or you miss those moments, and that lends intensity to the viewing experience; the avid fan, I have noted, is merely seeking to maximize the intensities of existence, as Spinoza taught. He or she gives himself over to football in an almost tantric way. It is a form of a fandom that requires, one might even argue, a philosophical attitude. I would say that—I’m paid to teach philosophy—but it also happens to be right.
Then every four years comes the World Cup, when, especially during the group stages of the first two weeks, one can justifiably maximize his or her intensities for an entire day, getting up only to eat something and stretch the legs. One match ends and—joy of joys—another one begins in an hour. Now, the fan knows that there are very few teams that are actually likely to win it all. Compared with the big American team sports—college basketball, NFL football, the NBA, etc.—in which there really are Cinderella stories, or at least unexpected champions, World Cup football really does tend to follow a script once the knockout stages begin. Since its inception in 1930, only eight nations have won the tournament, and a final without Brazil (five championships), Italy (four), or Germany (three) counts as a twist. The location of this World Cup makes its outcome even more predictable. On each of the seven occasions the World Cup has been held in the Americas (not forgetting the final in the Rose Bowl in Pasadena in 1994 and twice in Mexico City in 1970 and 1986), South American teams have won. Chile looks very useful and Uruguay plays like a resilient, coherent club team, but as much fun as it is to think about either winning, it’s really going to be either Brazil, if it can endure the pressure, or (my pick) Argentina. Along the way there will be a lot of rolling around on the grass, time-wasting, cynical tactics, and Mourinhian defensive displays. There will be triumph for a very few and righteous injustice and pain of defeat for the rest of us. But there will be this, too: Something unexpected, wonderful, and possibly even magical might happen. There will be grace.
