According to journalist Alfredo Pedulla, Juventus and Man United have agreed to a reimbursement of € 25 million (£ 21.5 million; $ 29 million) for the 25-year-old.
The reimbursement is supposed to be slightly less than the obligation to buy Chelsea in their loan agreement, from which they eventually came out for a fee of £ 5 million.
Chelsea wanted to keep Sancho in the club last season, but could not agree with a deal with the player who would be within their wage structure.
Juventus must be the conditions with the English international, but is supposed to offer him a salary of € 5 million (£ 4.3 million; $ 5.9 million), plus bonuses.
