selling a player - negotiating a price

[Tanuk]

i'm playing with anderlecht-belgium and i got marseille asking about vandamme.
How can i know what i can ask for my player?
he's worth 8 mil but i'd like to sell him for a bit more.

Is there a way to get other clubs to offer money instead of asking u how much u want for a player cause i only get those kinda offers

offer him to all clubs for £12m and see what happens

Tell them how much you want, one will eventually want to offer it.

Set a reasonable asking price.
