The term World Series of Soccer was initially a series of senior international soccer matches held by USSF between 1991 and 1994.
In 2005, Major League Soccer re-introduced the name for a series of professional matches in the United States.
National Team player pool for the 1991 World Series of Soccer:
In 1991, the United States Soccer Federation (USSF), established and promoted a series of national team games between the United States men's national soccer team and other national soccer teams. The goal was to provide U.S. soccer players on the national team an opportunity to play high level competitive soccer. The collapse of the North American Soccer League had removed the ability of U.S. players getting meaningful outdoor experience. While indoor soccer was booming, USSF didn't see it as an adequate replacement for outdoor competition when it came to preparing players for international outdoor soccer.
