According to an article on active.com, during a professional soccer game, the average player runs 6 miles during a 90 minute game. Which equates to a pace of 4 miles per hour, or 15 minute miles.
However, one interesting component of soccer is that the heart rate of the player is exceptionally high throughout the entire match due to the quick movements and change of pace that soccer entails, making it a great workout. My game tomorrow night is only 40 minutes, because it is indoor. But, chances are that game will net about 2 miles worth of running.
