Borussia Dortmund have warned Manchester United off making a move for highly-rated defender Neven Subotic.
Reports emanating from Germany claim the Red Devils have joined the long list of clubs tracking the Serbia international.
Subotic's future has been the subject of conjecture for some time, with the former Mainz man regarded as one of the best young defenders in world football.
Dortmund are keen to keep hold of the 21-year-old and club executive director Hans-Joachim Watzke insist they have no plans to sell him.
"Selling Neven Subotic is a non-issue," Joachim Watzke told Bild.
"If Manchester United is wanting to have him, they would need to sign over a property of two oil-fields to us.
"Or at least two big trucks full of packaged pound notes.
"We have no intention to sell the player, he is under contract."
Subotic claims he is not thinking about a move away from Dortmund, insisting he is happy at the club.
"It is no secret I am enjoying being a player of Borussia Dortmund," said Subotic.
"I feel bloody good being a part of the squad and have the big ambition to be sucessful with the club in Europe, too.
"Therefore I am actually not thinking about a transfer away from Borussia Dortmund."
