Sporting director Klaus Allofs has warned Arsenal and Manchester United that Wolfsburg no longer need to sell players like Kevin De Bruyne.
Having failed to impress under Jose Mourinho at Chelsea, the Belgium international has quickly established himself as one of the most impressive players in Europe since heading back to Germany.
He has a market transfer value of £36m with Wolfsburg determined to improve his contract to keep him at the Volkswagen Arena.
"Kevin's got a contract until 2019 so that's already a clear signal," Allofs told Sport1.de.
"He's staying with us.
"We've also said we're going to give his contract another look. It's about rewarding Kevin financially for his extraordinary development.
"We want to ensure that the best players we have get the best wages, which is why we're going to put something to him and I think we'll be quick in finding an agreement.
"Of course I would like to see him stay here until at least 2019, but what happens in a year's time depends on Kevin's development, but also quite decisively from Wolfsburg.
"If we are able to repeat what we did this year, then there are not many reasons to leave Wolfsburg."
