Borussia Dortmund have warned Manchester United they are in no mood to sell Jadon Sancho.
The youngster has netted eight goals and grabbed 10 assists for his side in 25 appearances.
It is his second full season in senior football, after moving from Manchester City in the summer of 2017.
There are reports United may be willing to pay as much as £100million for the player in the summer. But BVB sporting director Michael Zorc says the club will not sell.
"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," Zorc told Bild.
"Jadon will play at Dortmund next season and we are definitely planning with him."
