I think about a new competition format that motivates all players.
1) make the competition like real world. There will be all countries with all trophies like England premiere league, FA cup, seria A, and all countries have their leagues from premiere to the lowest league and cups. then new and current players decide which country they wanna join in and new players start in lowest league. (except cup that all clubs take part in one cup like every real cups).
2) there would be club cups like AFC champions league, Euro champions league, African, American and etc.
as you know, countries have different number of teams in championship. for example, Japan, south Korea, iran, have 4 clubs in Asian championship while some countries may have one (if their champion wins the qualifying match).
and if there be a club ranking based on winning, losing, final place and so in each competition (depends on how tough that league/cup is) players try to choose better leagues with better benefits not the easiest one.
3) champion of each continental goes for world club cups. and there we have the champion of the game!
4)the manager who become the champion of each country premiere league, becomes the manager of the national team and with advice of other managers, chooses players and there we would have national teams competition.
This idea needs hard working but I'm 100 percent sure it makes the game the most manager simulation game ever!
