It's difficult to preview a match on Sunday when the teams involved are both engaged elsewhere on the Thursday leading up to it. The results of the Thursday games can have a major effect on the Sunday game, not just in terms of confidence and fatigue, but also will-to-win—why would Mexico even bother if they lose to Panama later today?
But that's what us sports journalists do: We predict results and preview games, all so we can get slaughtered in the comments when the score goes completely the other way and a goalkeeper nets a brace from consecutive corners.
So here's a look at Sunday's matchup of tiny island nation Martinique against current Gold Cup and Olympics holders Mexico.
If you want a tiny inkling of how unpredictable this tournament is already, how about this: In group A, Martinique sit second on three points, having beaten Canada in the first game, while Mexico recover from a defeat by Panama on zero. Mental, eh?
