Hello
I noticed that when you put a player to the transfer list even if he will not be sold your merchandise is decreasing (Player Jersey sales becomes 0)
After how many times if you put him to the transfer list his sales become 0? or at the 1st time ?
No, it is not correct.
for merchandise players (jersey sales) there are 2 rules:
1 - For receive mercha from a player, he MUST BE play almost half of a game of season (you can see the exact number in league page, in the header of players statistics where there is write the numer of games).
If a player not played almost that numer of games, you will sell 0.
2 - mercha players are influence of his statistics, if he is in a higher position of statistics of a league player, most jerseys sell
If you put a player in a transfer list, you will see the fan survevy decrease (the balls in fan page)
