USA won their second game yesterday, so they should be progressing to the knockout stage. Scotland, however, have never reached the knockout stage and will have to wait until their last game after losing yesterday.
At the World Cup, players play for their country, but on a weekly basis, 154 of them play in the English Premier League, 94 in the German Bundesliga, 78 in the French Ligue 1, 74 in the Spanish La Liga and 68 in the Italian Serie A. The ninth highest with 37 is England's second division, the EFL Championship.
I haven't watched any yet, but been keeping an eye on the scores. I'll probably watch a few over the weekend. I'm not a huge soccer (or what most of the world calls football) fan, but I catch a game every so often when I'm at my sister's house. One of my nieces played soccer throughout high school and I watched her games.
