I totally agree with shomyguca.
Really ? 4M for a player close to his maximum and with an actual level of 59 (Very Good morale) ?
He wouldn't leave for 3M, probably. Not even sure for 2M.
Another of your players on the market is as insane as this one.
4,8M for Thorstein Johansen : 21 year old, Value 600k and actual level 56.
Ok, it is a LA 9 (PR 3), but he is already 21, and he will barely reach CA 8. He should be sold something between 1 and 2M, not more.
So, I am really sorry for you mistake, but if you can sell your players with an excessive and unrealistic prize to naive people, you can also accept this issue without complaining.
