Bayern Munich have informed Manchester United of their asking price for Jerome Boateng.
The Manchester Evening News says Bayern will accept £50m for the Germany international.
Boateng is currently in Russia with his national team as they look to recover from their opening-game defeat by Mexico.
United had also been interested in Barcelona defender Samuel Umtiti but the Frenchman committed his future to the Catalan giants.
Boateng has previously spoken of his desire to return to the Premier League having spent a season at United's bitter rivals Manchester City in 2010.
