Wolfsburg chief Klaus Allofs accepts they're a stepping stone for Kevin De Bruyne.

The Belgian is a major target for Manchester City this summer.

Allofs told Sky Sports: "The situation is unchanged.

"So it's the latest one but we don't want to sell him. As everybody knows he has a contract until 2019. We have not had serious offers, written offers but I know that there are some clubs are interested, this is not a secret.

"He's happy with us, I think he made the right choice when he came to Wolfsburg and he was not so happy with Chelsea, he was not a titular player, and he made the right step for him, and it was also the right step for Wolfsburg and now he is happy.

"And we know we were not going to keep him until 2019, and even not until 2018 but he's played just one-and-a-half years with us and so I think even if he stays, and this is very probably the case, he will be happy."
