I have done this once before and got results, decided to try it again, since this is the 7th offer for this player in the past 2 days. I found the player on Facebook and messaged him:
This is <redacted> of Top 11. You made a bid on my player <redacted> of ZERO tokens. I do not sell anyone for ZERO tokens, especially when they are five star players with one skill point away from scout and with a special ability. Would you sell this type of player for nothing? IF not, then why ask me to have him for nothing? He cost me 18 tokens to buy him from another player, and you want to get him 2 days after I buy him and I lose 18 tokens?? What did you drop to make this offer? 8-9 tokens? Again, I paid 18 tokens. And it took me 10 days of constantly making the offer in order to persuade the guy to sell him. Another fact: the seller did not need him - the player was 1* to him and he increased his skills in order to make tokens. He made 5 tokens on the sale. You are asking me to make ZERO tokens on the sale to you. NOT GOING TO HAPPEN!
In the future, try offering 2-3 tokens to the player you want to buy from and maybe, just maybe they might sell to you.
Also, you should check to see if I need the player first, and if I need him, why would I sell him? Use the grey matter God gave you next time you make an offer and you wont be insulting other managers.
Now, I would update the game to fix this situation by increasing the cost every time the seller denies the sale.
Example: the player offers ZERO tokens, costing him 8 tokens total. I reject the transaction and the next time he tries to make an offer, it automatically goes to 1 token + the mandatory 8 + the 1 token for the Nordeus cut, for a total of 10 tokens. and if I reject that, it goes to 2 tokens + the mandatory 8 + the 2 tokens for the Nordeus cut for a total of 12 tokens, etc. This way you dont constantly get ZERO token offers.
