I don't think the player flags are working properly on the Roster page or in the Player Information page.
I can see my first 2 players on my list are shown as German but the rest of the players in the Roster are ALL shown as Italian.
Most of my team is Italian yes but I know I have brought 3 Germans, 2 Americans, a Canadian and a Brazillian. I can see my players previous games for teams in those countries.
Just a small bug, but I thought you may not have spotted it.
