Have you seen that moment where the captains exchange the team pennants?
Ive been thinking in the old Flags page we had inside top eleven, these times where we could collect flags of our oppos nationalities, and Ive been thinking that we could have something similar.
For example, we could be allowed to select a FA emblem once per season,and we could complete a collection of pennants just for playing vs a FA with a specific emblem, or... as it's well known that the game added GK shirts, we can have a new element, but it should be rare and have a double function.... like be mainly shown if we owe it, and be shown in a gallery or inside the profile like the achievements if was earned due a match vs a oppo....
So the tours, we won, could have a exclusive pennant, shop could have, few rare designs, FA emblems can be converted themselves into pennants so once we face X FA, we exchange both pennants for our collections, etc.... yeah would be just a visual element.
