If you were one of the U.S. soccer fans who cheered Jesse Marsch and his Leeds team as they avoided relegation in the Premier League, you will love Voice of the Game. It is a wonderful documentary by Tom McCabe and Kirk Rudell that spotlights Manfred “Manny” Schellscheidt, a German immigrant who came to play and teach soccer in one of the game’s last frontiers, America. He may well be the least known, and most important coach in American soccer history. And coaches like Marsch are continuing the vision of the game that Manny installed in them.
