Wolfsburg sporting director Klaus Allofs has revealed Manchester City have made an offer for Kevin De Bruyne.

The Belgian attacking midfielder has been strongly linked with City for the entire summer transfer window and it has now been declared that the Premier League club have indeed tabled a big-money bid.

It is believed that an agreement has been made between the two clubs which will see 24-year-old De Bruyne move to Manchester before the close of the market next week.

Allows said: "He's had an astonishing, astonishing offer from City and we can't compete with that.

"We had to take it seriously and that is the way we react with our players and finally we decided to start negotiations with City.

"During the day we have gone on with negotiations and we've got closer to each other. But the deal is not already done. So hopefully we will find an end tonight or tomorrow morning.

"I would prefer to keep him, not to get the money. But the money now is really the issue because Kevin was qualified with Wolfsburg for the Champions League and he was a key player and took the next step.

"At Chelsea he was not that good and I know the story because I took him to Werder Bremen two years before and then to Wolfsburg. It will be very difficult - apart from Bayern Munich - to compete with the Premier League in the future.

"It is a big blow if he is leaving Wolfsburg but, you know, it's a difficult situation. Have a look at the statistics. Kevin did I don't know how many assists and he scored 10 goals so he was, he still is, a key player for Wolfsburg. It's really a situation that nobody was thinking about when he started with us."

It is believed City's proposal could see the fee for De Bruyne rise to as much as £55million and will land the former Chelsea man around £200,000-a-week.
