Twice World Cup winners Argentina lead Group F with six points and have already qualified. (Agencies)
To win the group they need at least a draw against the Africa champions, who is at the second position with four points and the only team yet to concede a goal.
Argentina's much-vaunted attack, led by Lionel Messi, have scored just three goals in two matches as they squeaked past debutants Bosnia and unfancied Iran.
Nigeria could win the group with a victory over Argentina and need a draw to advance.
Iran, with one point, could still qualify for the round of 16 with a win over Bosnia if Argentina beat Nigeria.
France, with two wins from two, does not yet have mathematical certainty of a last 16 place.
It would take a heavy Ecuador defeat of 'Les Bleus' and a big win from Switzerland over Honduras to cause that unlikely scenario.
Should France win or draw against Ecuador, they would top the group and face the runners up of Group F in the knockout stage.
The Swiss will hope that France beat Ecuador, which would mean a draw or win against Honduras would lift them to second.
