We pay people 10s of millions to make those decisions mate, you are weighing what you loose vs the market and how you can improve - the market is now limited - its at its end. Personally i think its stupid to sell him, because its to much to loose Richarlison and Gordon and i dont think you are replacing either with quality at this stage of the window - the market is now limited.
I don't see Chelsea throwing their best young talents at us in this deal, despite having more riches then us, why? Because its a bad footballing and business decision.
Ive no doubt this situation is holding up other deals - if you are Ajax or PSG what's the rush on negotiations if the team you are doing a deal with are going to have 60 mill by the end of the week - you'd fleece them.
