i have 2 matches scheduled back to back, 15 mins apart from each other. which is ridiculous! No team in real life plays matches this close. I think the developers should look at scheduling much closely. This is my suggestion.
In the game, 1 day = 1 week in real life. The ratio is 1:7. In real life games, the minimum rest you are looking at is about 3-4 days. Mostly league/cup matches on weekends, continental on weekdays. Of course there are exceptions here and there, but this is the rule of thumb.
So, to simulate more accurately, 3 days of rest in real life equates to about 10 hours of game time, and that should be the amount of time given in the game time. It's ridiculous for 15 mins of time apart for games. I understand you cn pay tokens to change matches, just note my matches are both AWAY matches. i cant change.
TLDR : Minimum time between games should be 10 hours.
