The 17 year-old prospect has been likened to new Bayern Munich defender Dayot Upamecano.

Under contract until 2023, he is already estimated at around €6m by his club.

And Foot Mercato says Juventus, Barçelona and Arsenal are among clubs keen on Doukoure.

The youngster has big ambitions and already employs a physical trainer, a nutritionist and a press officer.
