Merry Christmas all, although it a bit late, I hope you all had a good one.
Also, Magic, I have some club ideas for major CONCACAF clubs in addition to Chivas, Saprissa, and the ones you have...
Alajuelense (Costa Rica)
CD Olimpia (Honduras)
Cruz Azul (Mexico)
Defence Force FC (Trinidad and Tobago)
If you wanted a Jamaican club I would say Harbour View or Tivoli Gardens. I could help you with some of these too.
EDIT: I have done profiles for Cruz Azul, Alajuelense, and Defence Force, as well as SV Transvaal of Suriname, who are actually bigger in CONCACAF than I thought. SV Robinhood is another big club from Surinam with more domestic, and have been Champions Cup finalists 5 times without winning, so I might do something on them as well. I can PM the profiles to you if you want.
