England forward Jadon Sancho will remain a Borussia Dortmund player next season, says the club's sporting director Michael Zorc.
The 20-year-old has been named in the Bundesliga club's squad for this week's training camp in Switzerland.
It comes on the day of the deadline set by Dortmund for any deal to be agreed for Sancho, who is Manchester United's top summer target.
"We plan on having Jadon Sancho in our team this season," said Zorc.
"The decision is final. I think that answers all our questions.
"Last summer we adjusted Jadon's salary to match the development of his performances. So in context, we had already extended his contract until 2023 back then."
Dortmund want about £100m for Sancho, who they signed from Manchester City for £10m in 2017.
Sancho and England Under-17 midfielder Jude Bellingham are among 31 players to travel to Bad Ragaz.
Bellingham, 17, joined Dortmund from Championship side Birmingham City in July.
Dortmund have two matches during their training camp, against Austrian sides SCR Altach on Wednesday and Austria Vienna on Sunday.
They set the deadline for Sancho, who is under contract with them until 2022, because they want undisturbed preparation for the 2020-21 Bundesliga season.
The new campaign starts on 18 September, with the transfer deadline for international deals on 5 October.
