It gets better:
Apparently, Grenada told FIFA that the 2nd match would be the unofficial match, and the first would be the A match.
They subsequently posted the complete opposite on their Facebook page - U-23 match on 8 June, "A" match on 10 June, .
Bermuda don't seem to know anything about it and seem to be preparing for 2 "A" matches....
I seriously doubt Bermuda will send 2 squads to Grenada.
A really stupid rule this "3 days between matches during FIFA friendly dates". It applies to women's matches as well. Women's teams in particular had been used to arranging 2 matches, with only 2 days between them, to cut down on accommodation costs. This rule now forces them to either play just 1 game, stay for 3 days in the host country, or choose to play outside FIFA friendly match dates (where they can play 5 matches in 5 days if they want).
