World Cup 2014 Group'F': How can the teams qualify?

Ahead of the final round of fixtures in Group F, we look at the various permutations.
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.
