the difference between 5-3-2 and 4-3-3 was clear as night and day for Argentina. I read Sabella beforehand explaining why he intended to switch, but hopefully he'll see sense and stick with the 4-3-3 from now on.
Italy were never behind against England, and Argentina looked to be coasting against Bosnia. They might have slipped up late on, but I think they had a few more gears available.
