World Cup: Argentina vs Iceland, 8 a.m. Saturday, Ch. 9. Iceland has one of the most cohesive teams in this tournament, but you probably can’t name a single player on it (unless you’re a huge Gylfi Sigurdsson fan). Argentina isn’t as good as in past tournaments but still has Lionel Messi, and that’s probably enough to beat Iceland.

World Cup: Croatia vs. Nigeria, 2 p.m. Saturday, FS1. This genuinely could be one of the most interesting games of the first round. Nigeria might be the best of the African teams, while Croatia doesn’t have a big international reputation but does have a star-studded squad. This game could decide one of the qualifying teams from Group D.

World Cup: Costa Rica vs. Serbia, 7 a.m. Sunday, Ch. 9. If Costa Rica is going to get out of Group E, it very much needs a win against Serbia — especially with games against Brazil and Switzerland coming up. Serbia, meanwhile, will feel the same. A loss in this game, and either team will feel almost as if its World Cup is over.

World Cup: Germany vs. Mexico, 10 a.m. Sunday, FS1. Everyone expects Germany to cruise, because that’s what Germany does. Mexico, though, has the talent and attack to give Germany problems and take control of crowded Group F.
