The issue facing Berrada/Hargreaves in negotiations and Ashworth/Ten Hag in relating to the question Sancho in/out/replacements/etc, probably isn’t so much finding out Juve’s hidden intentions, but rather finding out how much it is worth getting rid of Sancho vs the cost of keeping him. If nobody can be lured into paying more than a pittance for him after a year of trying, then it seems likely that the whole world sees him as spoilt goods and there’s not much we can do about that. If he is unwilling to go radically down in wages in order to play, we can sit on his contract and leave him in the skids while he gets rich watching his carreer go down the pisser, but if that’s what drives him, there isn’t much to do about that either.
To me, Sancho was an unlucky contract signed, the money is best regarded as wasted and anything we can bring in is a bonus, like with Greenwood. The lesson must be to learn how to detect people like that and avvoid make such contracts with them in the future.
