Borussia Dortmund sporting director Michael Zorc has ruled out the possibility of Jadon Sancho leaving the club to join Manchester United this summer.
The Red Devils are understood to have made Sancho one of their top transfer targets when the window reopens, leading to speculation linking them with a British-record £100m move for the former Manchester City youngster.
However, Zorc insists that the 18-year-old is not for sale and hinted that no club in the world would be able to offer enough to convince them to sell the winger.
When asked about the speculation linking Sancho to United, Zorc told Bild: "I don't know anything about that and it has no relevance.
"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."
Sancho has enjoyed a breakthrough season for Dortmund this term, directly contributing to 20 goals in 26 Bundesliga appearances.
