"Playing soccer well depends little on having good ideas."

This statement seems to me to be profoundly wrong.

Perhaps some ways of "playing soccer well" depend little on having good ideas. But soccer is a very complex game: the configuration space of the players on the field is ~2*11 dimensional per team (add the z dimension for jumping and the ball in the air and you see that the total coordinate and momentum space is even vaster than 44 dimensions). Good teams are capable of organizing into configurations on the fly which are more likely to lead to goal than other configurations, and they can do this in response to the configuration of the opposing team. The Spanish team that won the most recent World Cup is a great example of 11 players who self-organize into optimal configurations in real-time.

You might argue that some players can use pure athleticism to navigate through the 44+ dimensional space and score goals. Lionel Messi and Diego Maradona are great examples: see http://www.youtube.com/watch?v=JYet49BToLw. They share a unique build which is suited to their style of soccer playing. They are not tall, have a low center of gravity, they can accelerate and pivot very quickly, and still they have a high top speed. That allows them to make runs like those "Goals of the Century" in the linked video in which they single-handedly beat the opposing team to a score.

However I would still hesitate to say that Messi and Maradona don't need good ideas to make those runs. Exactly where they choose to run probably depends strongly on where the defenders are relative to the ball-carrier's position. Also how fast they choose to run at any moment can depend on how fast those defenders are moving--hence the utility of pivot moves. Watch Messi beat the defender that comes at him from behind at 36-37 seconds, shown from another angle at 48-49 seconds; Messi gives the illusion that he has eyes in the back of his head. But really he has played soccer so much that he can take one glace around the field and calculate which defenders can reach his position and how fast they must be moving and in what direction in order to do so. This is not a trivial calculation to do at the rapid speed required by the game.

One of my favorite positions to play is Center Midfield. This midfielder often has more control than any other player to influence to configuration space of his team. One of my favorite players to watch do this was the brilliant Zinedine Zidane. He was a technically gifted footballer, but that's a relatively small part of why I loved watching him. The main reason is because of his perspicacity and decision-making skills. It is not just as if he has eyes in the back of his head; it is as if he can see the game as we spectators see it, with a birds-eye view. His brain is closer some kind of soccer video game AI that can calculate the optimal place to put the ball based on current configuration of the 22 players.

One of my favorite matches was Zidane vs. Brazil in 2006: http://www.youtube.com/watch?v=SvYlvkWpPy4. Check out what Zidane does at 2:05-2:20. France is already up (on a Zidane assisted goal), so they do not need to score a goal. Still they would rather keep play near the opposing team's goal for the chance to score again and to decrease the likelihood of Brazil equalizing. So Zidane is basically playing keep away for the win. At 2:14 Zidane makes a hand gesture, directing a teammate into the space to his right. Brazil players respond, moving towards the space. Then he makes a pass in the completely opposite direction, which is probably what he planned to do all along. Possession is maintained by France and the clock ticks closer towards their victory.

Truly beautiful.
