The 21-year-old winger is reportedly available for €100 million.
Manchester United were repeatedly linked with Sancho ahead of the 2020-21 campaign until Dortmund sporting director Michael Zorc formally called off a potential switch on the first day of his team's training camp in Switzerland last August. The German side then tweeted an image of Sancho in his Dortmund training wear with the caption, "You love to see it."
However, subsequent accounts suggested Sancho stayed at Dortmund due to United backing out of a transfer, rather than Zorc aborting the negotiations. The English club was apparently deterred by a deal that could've been worth close to €250 million after meeting Sancho's previous asking price of €120 million, paying him a competitive salary, and covering a commission to the player and his agent.
Zorc told ARD TV on Saturday that Sancho will be allowed to leave "under certain conditions" this summer, Uersfeld reports. Zorc also said a "gentleman's agreement" was struck with Sancho last summer that allowed him to leave after this season.
Sancho has dealt with injury problems and a loss of form at the start of the campaign, but has still contributed six goals and nine assists in the Bundesliga and two goals and three assists in the Champions League.
Overall, he's made 133 appearances for Dortmund, notching 46 goals and 62 assists since moving to the Westfalenstadion from Manchester City in 2017.
