Leeds United have been linked with the young winger.
If he does put pen to paper at Elland Road, he will join fellow loanee Kyle Bartley and permanent signing Marcus Antonsson in joining Garry Monk’s new-look squad, and while not much is known about the player he has some experience of playing in both Ligue 1 and the Europa League.
Formerly on the books at Bordeaux, Le Havre and Sochaux-Montbeliard, Sacko is predominantly a right winger although he can also operate on the opposite flank, as a secondary striker or as a centre forward if required.
If the latest reports are true, Sacko will be hoping to use Leeds’ pre-season tour of Ireland to impress Monk and earn a contract in the process, and given the club’s need to strengthen out wide he will not want to let this opportunity pass him by.
