Juventus halted Sancho transfer because they just signed Francisco Conceicao, and they don't have enough funds to sign Sancho. They're planning on selling one of their winger in order for them to raise funds for the signing of Sancho. If Juventus did not succeed on selling either Nico Gonzalez or Timothy Weah, they might not be able to bring Sancho in. No club wants to add more players to their squad without selling to replace.
That's part of the move Juventus must make, but if it doesn't work out for Juventus, Sancho might be a little hesitant if other teams don't consider him in his current situation. And I completely understand Juventus' decision, as Juventus' financial situation is limited, so selling existing players to bring in new ones is a common solution for every team. I only hope Sancho can move to another team from Manchester United if he is truly no longer needed by Manchester United next season.
Sancho future is really uncertain it because Manchester United is not need him anymore and the latest is Amorim didn't bring him for pre season tour and moved to Juventus could be another option but unfortunately Juventus have already to permanent Francisco Conceicao status from Porto with 32 million and you says is true that financial condition of Juventus is not really good although Sancho price is not expensive because Manchester United only want 15 million but i am doubt Juventus will do this transfer and in my opinion this transfer probably rejected especially Juventus has Francisco Conceicao who can in form when he was loaned
