Atlanta United got its first taste of Concacaf Champions League action and all the chicanery and weirdness that comes with it in a 3-1 loss to CS Herediano in Costa Rica Thursday night. The wind was blowing, the pitch was bouncy, the referee lost his notebook in the first half, and the lighting was questionable. But most of all, Atlanta United struggled to organize themselves defensively, conceding two first half goals and allowing even more quality chances throughout the match. Julian Gressel scratched one back late in the first half on a deflected shot, but Herediano added a third goal early in the second half to stem the tide.
