This is the one that everybody in the US is playing special attention to. It was thought that English speaking countries would waltz through to the knockout stages, leaving the smaller countries of Slovenia and Algeria in the dust. Boy was that wrong.
I actually theorized on a way that these countries could cause some mischief in an earlier entry, but I still didn't give them enough credit. Slovenia are in the driver's seat. A draw against England puts them through. A victory puts them through as group winners. They could lose and still go through depending on what happens in the other match.
England are through if they win, but need a lot of help if they draw. This is not an ideal situation, but they do still control their own destiny.
Algeria need to win and hope that England don't win.
The US are in with a win. They need help if they draw, but likely go through ahead of England if both draw.
It will be an interesting Wednesday morning, to say the least.
