The following information is from Wikipedia: From 1997 to 2008 there haver been 11 Champions' Cups, one in every year except 2001. I started with 1997, the year MLS teams started participating. Every Champions' Cup has started with 8 teams except for two that started with 16. 1. Mexico has 20 semifinal appearances out of the 44 possible during that time. MLS has 14, Costa Rica has 9, and CD Olimpia from Honduras in 2000 is the only team from any other country to win in the quarterfinals or later. Mexico has had over 75% of their quarterfinalists make the semifinals. Costa Rica has had 60 percent, and MLS a little better than that. The 25 quarterfinal appearances by teams from other countries yielded the 1 aforementioned quarterfinal victor by CD Olimpia. 2. A majority of the 37 different clubs to make the quarterfinals during that time have come from Mexico (12) or MLS (7). Here is a list of the 11 clubs with 3 or more quarterfinal appearances: D.C. United (USA): 7 Alajuelense (Costa Rica): 7 (I was surprised they had more appearances than the next team) Deportivo Saprissa (Costa Rica): 6 Toluca (Mexico): 5 CF Pachuca (Mexico): 5 CD Olimpia (Honduras): 5 San Jose Earthquakes/Houston Dynamo (USA): 4 Los Angeles Galaxy (USA): 4 Chicago Fire (USA): 3 Municipal (Guatemala): 3 Joe Public (Trinidad and Tobago): 3 The four remaining clubs in 2008 have all made at least 4 of the last 11 Champions' Cups. Later I plan on posting more about such things as average rounds advanced for countries and for clubs with several appearances.
