What's the Point of a Negotiation?

Liverpool have put an offer on the table for mohammed salah, according to reports. The Reds are yet to decide whether or not they will let him leave this summer. Salah is holding out for the best price that he possibly can and liverpool won't be prepared to go over it in terms of moving forward their sporting project. But i think amfield bosses already have a budget in mind for what they will actually be prepared to pay sala. And i daresay, not what he was offered.
