An interesting weekend.  Portugal booked a place in the Round of 16 in unconvincing fashion, but they did get a nice goal from 
Deco.  At the same  time, Iran was eliminated.  The other place from Group D will go to Mexico or Angola, who played out a disappointing tie.  Mexico have the points, but can be overhauled by Angola if they lose and Angola beat Iran by enough to overhaul the 3 goal deficit.
If sure you're familiar with what befell Team USA.  Bottom line, they have to beat Ghana and look to Italy to beat the Czechs.  That'll put Italy and the US through, regardless of goal differences.  If Italy fail to beat CR, then the US will need to put a few past Ghana and trust to luck.
Brazil, like England, booked a place in the next round with a second unconvincing win over the plucky and unlucky Aussies.  Japan are all-but dead, needing to beat Brazil to have a chance of moving on.  Australia and Croatia play each other in their last group game, and the winner will move on with Brazil.
France hilariously played like shit against South Korea.  Their second poor performance sees them looking up at S. Korea and Switzerland with a game to play.  France need to beat the eliminated Togolese by 2 goals, which will see France overhaul one of the top two regardless of the result between SK and the Swiss.  If France lose or tie, they're done.
The last of the Game #2s are today, but Spain are cruising in Group H and I don't really think anyone cares about who moves on out of Saudi Arabia, Tunisia and Ukraine.
Now things start to get good.  There will be four games a day between Tuesday and Friday as the group phase wraps up.  The last round of games in each group kick off  simultaneously, and there are many "win or go home" scenarios to be played out.
Tomorrow, Germany and Ecuador play to decide the winner and runner-up of Group A.  Later, England play Switzerland in similar circumstances in Group B.  Switzerland can still be caught by Trinidad & Tobago if they lose, but Tuesday's games aren't full of the frenzied mathematics that will play out later in the week.
Mexico and the USA face their days of destiny on Wednesday and Thursday respectively.  France are under the gun on Friday.
