The Germans’ analysis of “Big Data” derived from detailed video monitoring of thousands of data points per second pertaining to each player’s on-field activity, using a proprietary system called “Match Insights,” allowed them to eventually decide to emphasize team speed. As a result, they cut their average time of possession from 3.4 to 1.1 seconds. Also as a result, though Brazil actually possessed the ball more than Germany (52% of playing time), the Brazilians had almost no opportunities to score.
It appears that the Match Insights analytical tool may soon be available to others. See this excellent article at: http://on.wsj.com/W2J8LL
