argentina just need to draw against nigeria to secure the top of their group while nigeria on four points would appreciate if bosnia knocked off iran who have a chance to advance should nigeria lose and they win. after that comes down to goal differential. argentina could use a solid victory going into the next round as they have yet to impress beyond a couple of game savers from messi.
late games have france v. ecuador and the swiss v. honduras. france have not yet advanced on six points but they have a considerable goal differential buffer so only a massive defeat coupled with a huge win by the swiss will keep them out. so switzerland have the advantage in their present tie at three points with ecuador as they have the easier match with honduras. though ecuador will advance on goals if they both tie in their matches today.
likely outcome then is that argentina, nigeria, france and switzerland advance.
