I still think Cuba, Haiti, Jamaica, and Trinidad & Tobago are the CFU Elite, however i've noticed that the reggae boyz as well as the soca warriors have been recently struggling against their lesser known opponents from Barbados, St. Vincent & the Grenadines, Grenada, and St. Kitts & Nevis.
To be more successful, what they need to do is to forget all this legacy crap and play to their abilities.
