Dortmund, to start with, wants him back. That makes sense. He's at ease there and they know his talent. Given their difficulties getting rid of him, United might be tempted by that. Second, United wants to sell, not loan. Sancho was overpaid for, and they want some of that money back. A loan deal doesn't help them with that.
Juve has to make a strong offer. A great one. And I dont know if Juve is willing to pay top dollar. They've got other priorities, other players they need to focus on.
Im not saying its impossible, but I wouldnt bet on it. If I were you, I'd keep my expectations low. Both ways could happen with this, and Juve doesn't seem to be doing well at the moment.
Well in terms of finances I don't know how well Juve may be, but they need someone like Sancho, they really need it, in fact the only lie is that as you say, if they don't have the money to buy him they won't give him away at least, I wouldn't do it either, in fact I wouldn't leave that player, now, I think Italy needs him a lot, because Juve have to invest to see results, let's remember everything they suffered to get to 4th, where they almost lost that position, they can't waste all that effort because they are only saving, no, they have to make an additional effort but they have to strengthen themselves.
On the one hand, Dortmund also will not be silent to defend the player because Dortmund has felt how Sancho's contribution after successfully reaching the final round and he made a huge contribution while with Dortmund and Dortmund's management will try to marry the player to become a long-term investment very profitable.
Currently Juventus have to think realistically than having to suffer bad luck not to win any title in the next season because competition in series A will be tighter after a small club under Juventus has a big change from the recruitment of new players who can give threats for Juventus and if in this transfer season Juventus cannot make many changes, Juventus' performance will only end like last season.
