Borussia Dortmund chief Michael Zorc has reiterated the club's stance on Jadon Sancho.
The 19-year-old is one of Manchester United's primary transfer targets for next summer.
Zorc also revealed that Dortmund had recently rejected a meeting with United to talk about a potential deal for the England international.
"We didn't talk to them [United]," Zorc told Viasport.
"They were asking us for a meeting [during the off-season]. Sancho is not for sale."
