A relatively straightforward group, but that means it will hopefully be one full of goals and full of heartbreaking underdog stories, which is always memorable.
Argentina - what a lucky draw they have had. Argentina have absolutely no competition in their group, and anything but 9 points would be a major surprise as far as I'm concerned. Any losses would be a significant upset. There's not much else to say really - Argentina are appearing in the group as a formality. It will be nice to watch them play the three matches at least, always such an entertaining side.
Bosnia - A brand new team, but plenty will make the mistake of judging debutantes as cut-and-dried losers. However, time has proved that is not always the case (North Korea in 66, Senegal in 02, and Ghana in 10) and Bosnia should come second in the group barring any major wobbles. Bosnia may have come out of nowhere but are certainly in a different league to Nigeria and Iran. A loss against Argentina is inevitable, but otherwise, the sky's the limit.
Nigeria - The perennial African front-runners (well, other than Cameroon), Nigeria have never been lucky in the World Cup and this is not looking to be their year. Argentina are impenetrable by Nigeria and Bosnia will prove too heavy for this middling set of players, in all likelihood. However, they can achieve victory against Iran and leave with their heads held high.
Iran - One of the weakest sides in the tournament and despite a fairly good draw, they cannot compete with Bosnia and certainly not with Argentina. Even Nigeria may prove too much for them. However, Iran are a side that have potential, and a few points is possible.
Predictions:
Argentina - 9
Bosnia - 6
Nigeria - 3
Iran - 0
