Mamadou Sakho and France aren't quite mathematically through yet despite their six points, but with a +6 goal differential edge on Ecuador and +8 on Switzerland, they're all but guaranteed to end group play first in Group E. Ecuador and Switzerland both sit on three points, and both will feel as though a win today will see them through. It might not, though, as if both win there would be three countries on six points, and that means both games will be key in determining who advances.
Switzerland would seem more likely to win their match, but they also have the worst goal differential and some ground to make up on that front. Ecuador, meanwhile, will have a hard time against the high flying French—arguably the tournament's standouts so far. France's goal differential edge may mean they're likely safe, but a result today makes it certain, and there's no reason to think they won't be out for more goals. That all adds up to the potential for a pair of fun, high-scoring matches. And more than a touch of uncertainty, especially for Ecuador and Switzerland.
