Another suggestion from me would be to create 
player transfers in real time! 
That is, when you want to sell a player
 to have time to set, I want to list the
 player on the transfer market: 
in one hour/3 hours/6 hours/24 hours or days!!!
Otherwise it would look like the transfer
 market would be much more captivating
 and attractive, what I suggested can be
 found in the Fifa game from 15 years ago!!!
