This is my second part of the Contract Negotiations.

When a player is "bought" through any of the systems of buying players, you will go another phase where you negotiate with the player.
I put quotations on "bought" as the player haven't started negotiating. So, your tokens and money won't be deducted until the player reaching an agreement with you.

If the player agrees with the terms you put, you could sign the player. You can't simply fall out of a deal if you change your mind.
If the player doesn't agree, they could, stop negotiations completely, and won't sign for you.

The player will not be sold to any other club and the auction will reset.

If a player feels like they are too good for the club, feel like they should be played more, or feels like the terms they set weren't fulfilled, they will email you saying so.
It could be time where you could choose to sell them or do what they ask you to do.

If you ignore them, it will affect their morale, and set a slightly lower possession bonus in matches.
It could also affect on how the team plays.

All of this would make you feel more a manager and actually doing the right/wrong thing.
Of course, I think this should happen not too much if you rotate the squad and keep them happy.

I don't want this to affect and make the manager under pressure.
