The Red Devils are scouring Europe in a bid to strengthen their attacking unit in the summer.
Sancho has shot to prominence since quitting Manchester City for the Bundesliga in 2017.
The 19-year-old starred in England’s 5-0 demolition of the Czech Republic on Friday night.
And United have reportedly made signing £100m-rated Sancho their priority once the transfer window opens this summer.
His statement comes after he recently said: “I’m far from putting a price tag on Jadon, but I will say that, even for the biggest club in the world, his transfer would be difficult right now.
“Jadon will play at Dortmund next season and we are definitely planning with him.”
The German giants are doing their best to dampen speculation regarding Sancho returning to the Premier League.
But former United defender Rio Ferdinand is adamant that the young attacker would be a great addition at Old Trafford.
The ex-England star told Goal: “I would take him [at Manchester United] all day.
“English, young, hungry and talented, that’s all I need to know.”
United may have to be patient in their pursuit of Sancho, but a glimmer of hope has been offered.
Zorc has conceded that a move will likely become possible at some stage, saying: “He certainly will not play until his retirement in Dortmund. That is true.”
Sancho penned a new deal with Dortmund back in October which sees him contracted at the club until 2022.
