Yes, I would like to see the Olympic jerseys added as an alternative options for national teams.
Even the old World Cup jerseys who was really nice would be a nice option to have as an alternative.
But to be honest, some of the olympic jerseys (like Canada and Switzerland) is really ugly so they better not take away the ones that are in the game now. 🙂
And yes, EA have not changed jersey, shorts or sock styles in Create a team for a long time now, so there is a need to add more options, because some real time jerseys, shorts and socks
are hard to create without the options.
