Manchester United target Ilkay Gundogan will reveal his future plans within the next few weeks, according to Borussia Dortmund CEO Hans-Joachim Watzke.
The German international has made just one appearance for Dortmund this season due to a back injury he picked up on the opening day of the campaign.
Manchester United remain interested in the deep-lying playmaker despite the fact he has been crocked for the majority of the season.
Gundogan, who has just one year left on his current deal in the summer, will reportedly make a decision on his long-term future in the next fortnight.
Speaking to the Daily Mirror, Watzke said on Gundogan: "On whether he will compete in the World Cup, I am not the one to give out reliable forecasts.
"We will not speculate about when he will come back. We are convinced he will be healthy but we cannot measure this in terms of weeks or months.
"As for the contract, it will not be a long, dragged-out affair. I think it is not going to be more than a matter of weeks."
Gundogan, who is said to be valued at around £25million, will be hoping he can get back to full fitness in time for this summer's World Cup in Brazil.
Manchester United are also said to be interested in signing Gundogan's international teammate Toni Kroos, as David Moyes has identified his midfield as the major weakness in his side.
