World cup UT

Ultimate team: live-events + challenges. Why not add a game-mode where you have to play with only players from the same country and a matching kit? That way you bring the world cup into ultimate team. You can also create a tournament where you let players who use only Mexicans face South Africa, South Korea & Czechia (their world cup group). If you get 4 points out of these games you go through to the knock out, where you face your next opponent. Something like that perhaps? You can perhaps make it locationbased so if my account is from Iran, I have to use an Iranian squad, maybe compensate for the difficulty by giving stronger rewards to Iranian squads that reach the second round in comparison to Brazilian squads.
