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.
Honestly, i don't understand what Juventus' player acquisition department is up to. They couldn't buy Osimhen, and Sancho said no. What's going on? i think they've run out of money and are bankrupt. Maybe i am wrong. However, these are very strange actions, honestly.
