AS Monaco face a battle to keep hold of young midfielder Mamadou Coulibaly.

The 17 year-old prospect is interesting Barcelona, reports Sport, but are not alone.

Manchester City, AC Milan, Juventus and Tottenham are also in contact with Coulibaly's minders about his plans.

ASM are fighting to keep hold of the prospect, with his semi-pro deal to expire in June.

As such, any interested club would only need to pay a modest compensation fee to ferry him away from ASM.
