IMHO Sweden Nigeria was more entertaining. 3-3 and Sweden needed 2 corners for it. The young Nigerians with their technique (I think it was 7 players from the U20 cup that played the cup's finale against Germany) made it obvious that Sweden has become to old, well at least Sweden didn't rely only on kick and rush, as before and one could get a small glimpse that they are slowly progressing.
The US girls have an average age of 29! They clearly profited from the experience (and their height) that the (small grown) Australian youngsters lacked. I mean, Australia wasn't a "finished/complete" team.
Rapinoe's goal e.g. was luck, that it first hit the back of the Australian defender. I mean they have long been the best, but their playing style is becoming old school and while still top, maybe one would expect to spend some money in youth training.
Well on the other hand, it would be boring if all teams played the same
I heard that the FIFA put Sweden, USA and Nigeria in one group, because they wanted Brazil to be the head of the other pot, to have South American viewers longer follow the tournament. Usually Sweden would have been the head of the other pot, that became Brazil's.
PS: US pals, don't get me wrong, I am not wanting to offend you.

Looking at the first minutes of Germany, they were playing under their capabilities, too and even later in the second half they missed some real sitters and placed them just next to the bar or posts. Given that they played against a team much worse than Australia, it might be even worse.
PPS: Update on Leupolz. Turned out she has a bruised pubic bone, after getting the knee in there (not the groin). She will miss the first round.
