Good evening,
As I indicated in the title, the idea would simply be to be able to indicate next to the player's name the starting XI to which he is attached. It would be more directly visible and more 'comfortable' to draw up the starting eleven.

Have a good evening.

Good evening

If I understand correctly, on your squad sheet, you want to indicate next to the name whether it is part of your A, B or C team?

I understand the same thing blue I think we're getting old lol

So... ^^' More concretely. You already have an A team, and you're in the process of preparing/modifying your B team. But as there's no indication of where you're attached to, you may be picking up players already in the A team, hence the suggestion that there should be this little extra indication next to the player names.
I hope I've made myself clearer. :)
Have a good evening.

OK, so you're asking what's already in the game that you probably didn't pay attention to.

When you go to tactics, at the top you have the starting eleven tab, then you click on the team you want to make (A, B or C) and you get this page where each column is a team.

The leftmost is team A
In the middle o team B
And the rightmost is team C
