Having completed match day 2 some groups have been clearly decided while others are still wide open, with some powerhouses (Argentina, Germany, Brazil) still fighting for survival.
Russia and Uruguay are through, not unexpected although Egypt with super star Salah was given an outside chance before the tournament. But they and Saudi Arabia will head home.
Favourites Spain and Portugal are in the driver’s seat. The only thing to create an upset would be a surprise Iranian win against Portugal in the last game. Although Morocco is eliminated, an unlikely win against Spain with an Iranian result against Portugal could give Spain a problem.
France is through and Denmark is in good position to advance as well. Australia is alive and needs a win against Peru coupled with a Denmark loss to France to have a chance to move on by virtue of goal difference.
Croatia is assured of a spot in the round of 16. After that it gets messy (or Messi?). Nigeria will advance with a win over Argentina. Argentina must win and hope that Iceland doesn’t pull off an upset over Croatia. Iceland still has a chance but must beat Croatia and hope for an Argentine win or tie.
The only thing we know for sure is that Costa Rica is eliminated. Brazil and Switzerland are leading the group with Serbia trailing by a point. As long as Brazil (v. Serbia) and Switzerland (v. Costa Rica) don’t lose their last game they advance. A Serbian win against Brazil will put Serbia through and likely knock Brazil out. A Switzerland loss to Costa Rica and a Serbia tie will put them on 4 points each and bring goal difference into play.
The only group in which everyone is still alive, even Korea with zero points. Mexico (v. Sweden) needs a tie to guarantee advancement. Germany needs to beat Korea by two goals to guarantee advancement. Sweden needs to beat Mexico by a bigger goal difference than Germany beats Korea to advance. That would knock Mexico out. Korea can advance with a win against Germany and a Sweden loss to Mexico.
Belgium and England are Through, Panama and Tunisia are out.
The only certainty is that Poland has been eliminated. Anyone of Senegal (v. Columbia), Columbia, or Japan (v. Poland) winning will advance.
