Why would they just fold and give us what we want, they are in no rush to get it done are they.
It is a game of chicken, City seem relaxed to let him go if an offer arrives because we have Ortega and Saudi are relaxed because there is no other competition for the signing and every week that goes by Ederson might be getting itchy feet and could turn on City and go on strike etc which could drive down the price.
Because they are not Barcelona. Because he might change his mind, and stay, or even sign an extension for more money here. And because what City are reportedly asking for is well reaspnable and they'll know it.
When have you known the Saudis to haggle and play chicken when they have a player convinced, they just do it and get that picture in a shirt up. I don't think this is as close as twitter makes out.
