Soccer teams have 15 MLS, and it was divided between the eastern and Western conferences. MLS allocated four marquee players across the initial ten teams before its maiden season. Inaugural allocations consisted of key U.S. national team and international players such as Eric Wynalda and Hugo Sánchez.
The league added its first two expansion teams for the 1998 season: Miami Fusion and Chicago Fire. However, following the 2001 season, Miami and the Tampa Bay Mutiny were disbanded and MLS returned to ten teams. Since the 2004 season, the league has expanded with six new clubs: Real Salt Lake and Chivas USA in 2005, the Houston Dynamo in 2006, and Toronto FC in 2007. After relocating as an expansion team to Houston in 2006, the San Jose Earthquakes returned from hiatus in 2008. Seattle Sounders FC joined MLS for the 2009 season.
As of 2009, MLS has had seventeen different clubs over the years, but only seven have won the MLS Cup.
These are the teams that have been aligned already for the 2009:
Eastern: Team
Chicago fire
Columbus Crew
D.C. United
Kansas City Wizards
New England Revolution
