i had the same question..i have 4 before next star,and was wondering when is the right time to sell.
I am waiting 2 days for any robot to make me offer but nothing.
Can u define why next season July ?
15-20% less price which u will get easily if u put him in rush hour to the TM.
But in higher levels i assume that managers Know the game better ,they search a lot.
In the other hand u sell him now (or wait for robot to make u offer till tomorrow) and have less rate for the cup..
don;t know which tactic is best
