Ahead of the final round of fixtures in Group F, we look at the various permutations.
The remaining games are Nigeria vs Argentina and Iran vs Bosnia-Herzegovina. Both kick off at 5pm and are on ITV.
Argentina – Qualified
Lionel Messi's late goal over Iran last week booked a place for the Argentinians in the last 16. A draw over second place Nigeria will see them top Group F.
Nigeria – Must draw with Argentina
A draw between Nigeria and Argentina will work well for both teams as the South Americans will win the group with the Africans guaranteeing their place in the knock-out stages. A win for Nigeria over Argentina will see them top Group F, sending Argentina into second place.
Iran – Need to beat Bosnia-Hercegovina and require Argentine win over Algeria, with a superior goal difference
After losing to Argentina in the cruellest fashion last week, the Iranians now rely on them to triumph over Algeria whilst making sure they beat Bosnia-Herzegovina in the process. Even then, Iran will need a superior goal difference to advance.
Bosnia-Herzegovina – Out
With two losses from two games, Bosnia-Herzegovina are guaranteed to be spectators following the conclusion of the group matches.
