Neither side is in imposing form. Martinique hosted the finals of the 2017 Caribbean Cup - and lost both its games. Nicaragua qualified for this tournament via a playoff with Haiti. The 3-0 win over Les Grenadiers that put Los Pinoleros into this Gold Cup was one of just two games they have won in 2017.
