Thought this might produce some interesting opinions. Pick a team, but pick each position by country. Any formation you want, but the position you pick for whichever country should have a history of quality players in that position representing the national team in question. So you can't pick Egypt for the right wing, just on the strength of Salah - got to be more players for that country that have performed there.
Here's what I've got, and it's not perfect. I would've preferred to have Argentina in the 10 spot, but then I couldn't make it work with the rest, so this will have to do.
