The competition, similar to that started by UEFA in 2018 and aimed at cutting down on meaningless friendlies, is part of a broad makeover by a confederation seeking to win back confidence of fans after it was ravaged by the FIFA corruption scandal.
At a gala ceremony in Las Vegas on Wednesday, CONCACAF’s 41 teams were drawn into three leagues, with the winners of the four League A groups competing for the Nations League title.
The top four sides in Leagues B and C will be promoted and the bottom four in A and B relegated for the next edition.
The group matches will be played in September, October and November 2019, with the finals taking place the following year.
