United chiefs have continued to push their interest in getting a deal over the line - with Ole Gunnar Solskjaer still keen to land his No.1 target and ex-City youngster Sancho keen on a return to Manchester.
Sancho, 20, missed Dortmund's German Super Cup defeat to Bayern Munich in midweek with a respiratory issue, further heightening speculation.
Asked about Sancho's future on Friday, Dortmund sporting director Michael Zorc once more made clear that BVB's position hasn't changed - insisting that Sancho will be going nowhere in the window's remaining days.
"Of course we communicated with Manchester United in the past," declared Zorc.
“But everything there is to tell on this matter from our end has already been said.
“And that won't change over the next three days."
