Defensively they have consolidated their position in the group but they are weak going forward, which is something they need to address in the final group game, if only the Argentinian's beat Nigeria with a good goal difference.

Actually the goal difference isnt that important, as if Argentina beat Nigeria 1-0 and Iran won 1-0 then both Iran and Nigeria would have the same goal difference so it goes down to goals scored which would be the same too so they would end up drawing lots.

Best thing Iran can do is win 2-0 and i reckon they could go through
