Last summer's transfer window was dominated by the long running saga as United tried, and miserably failed, to sign their number one target Sancho.
The club attempted several bids for the forward but wouldn't match Dortmund's asking price, believed to be around £110 million.
Interest in the 21-year-old reportedly remains at Old Trafford, with the Premier League side also potentially eyeing a move for his teammate Erling Haaland, and they have been handed a boost.
Dortmund sporting director, Michael Zorc, has confirmed that they have agreed with the former Manchester City youngster that he can leave this summer.
"We already had a gentlemen's agreement with Jadon last year that he can switch under certain conditions," Zorc told ARD .
"He's been with us for a couple of years. However, this agreement does not exist with Erling [Haaland]."
The player and the buying club reportedly had their proposals agreed last summer, with Dortmund allowing them to speak to Sancho.
That means that things would likely be pretty simple between those two parties again this summer, if Ole Gunnar Solskjaer's team did want to make another move.
The problem will once again come from the negotiations between the two sides, although there is a belief that the transfer fee could be lower this summer.
United fans won't be the only ones interested in the fact that Zorc mentioned that no such agreement is in place for Erling Haaland.
The 20-year-old only joined the German club from Red Bull Salzburg in January 2020 and his form since that move has made him a target for all the world's biggest sides.
Haaland's transfer release clause doesn't come into play until next season and the club don't want to lose him this season, even with the possibility they don't qualify for next season's Champions League.
The Norwegian's agent Mino Raiola has reportedly threatened to make his player move to Dortmund's rivals Bayern Munich next summer, if he isn't allowed to leave this year.
Real Madrid have claimed they can't afford Haaland but Raiola reckons that Zinedine Zidane's side can't afford not to sign him.
