The International Champions Cup (aka ICC) is a friendly club tournament held during the summer in the USA & Canada by local MLS host clubs. It gives big European clubs a chance to prepare for their upcoming seasons & grow their fanbase in North America, while MLS clubs benefit by having the rare opportunity to sharpen their skills against higher caliber international opponents as well as hosting high-attended lucrative fixtures.
The ICC is the evolution of the World Football Challenge (2009-12), World Series of Soccer (2005-7) and the privately promoted ChampionsWorld Series (2003-2005).
