Relying on youth players and the players who have now for the next season
I wonder if it is still possible to play the game and remain competitive with the same players you have this season and once you move up to a harder level...Also many say that youth players are best to be sold as they are revenue generators but if kept and assuming you have a full roster, can you still be competitive the following season? Let's assume you have one of the best teams in your league right now but as you know stars drops once you move to higher levels.
Basically can one remain competitive without spending any tokens in this game?
