Competition: MLS could face competition from another domestic soccer league.  Eight professional clubs in United Soccer Leagues, the organization controlling American soccer from the second-tier downward, are threatening to leave USL to form their own league.  The league would strive for a private ownership model, rather than an MLS-style collective.  It would feature teams in cities – such as St. Louis, Montreal, Atlanta, Minneapolis and Miami – where MLS does not have a club.
