He's a young, unmarried dude that probably grew up influenced by American culture and music, who is also not a Muslim. 99% people of who fit that profile are going to pick the US. Ask the same question when half a billion dollars are on the table and we'll see what happens.
We're only allowed one flair on here (I'm a dual citizen), so it isn't obvious, but I am a very patriotic American and love my country. I would move to Saudi for 10 million in a second, lol. Not even a question.
Obvious reasons in both cases, but in terms of football, it is a big blow for Burkina Faso and Guinea in particular. These are usually quite strong teams who have a bigger chance to qualify with it being 9 teams rather than 5. An away trip to Conakry or Ouagadougou is a tough task for any team on the continent. Won't be nearly as difficult on a neutral pitch.
