The youngster, who came through the ranks at Manchester City, has dazzled in Germany this season, scoring five goals and claiming seven assists to help Dortmund to top spot in the Bundesliga.
He has predictably attracted attention from top clubs and Man United, according to reports, are among the favourites to secure his signature.
But according to Sky Sports, Dortmund have absolutely no intention of selling Sancho in the near future.
The German club is under no pressure to sell Sancho after making a series of high profile sales – Ousmane Dembele and Pierre-Erik Aubameyang were sold for £160m – over the last 18 months.
Moreover, Sancho recently penned a new long term contract which does not contain a release clause, meaning Dortmund could quote whatever price they wanted for him.
Figures of over £100m have been quoted for Sancho, making him the most high-profile 18-year-old footballer in the world right now. United would have to launch an all-out assault to prize him away from a club where, frankly, he currently has no reason whatsoever to leave.
