The new managers of United and City both want the Borussia Dortmund striker, who is valued at £65million. That fee for Aubameyang, 26, would be a British record signing.
Arsenal have also been linked with the Gabon international but they are now concentrating on England striker Jamie Vardy, who has a £20m buy-out clause in his Leicester contract.
So unless there is a move by Real Madrid, the Manchester clubs are set to fight it out for Germany’s Footballer of the Year.
Sources close to Aubameyang have indicated two Premier League clubs are chasing the Dortmund star.
