Manchester United have reportedly entered the race to sign Borussia Dortmund star Pierre-Emerick Aubameyang, according to the Daily Mail.
The striker who has scored 22 goals in 18 games is being chased by Barcelona, Real Madrid, Arsenal and Chelsea too.
German paper BILD believe that a bid of £40million or more would be enough to tempt Borussia Dortmund into a sale.

Van Gaal believes that Aubameyang would add the necessary speed and power up front to deliver a title challenge in January.
But, with a number of other clubs ready to move United could face tough competition, especially as the striker has previously said he would much rather move to Spain.
This leaves Real Madrid as the outright favourites as Luis Enrique would be forced to play him second fiddle to Luis Suarez, Neymar and Lionel Messi.
