Despite starting the season as a 17-year-old the centre-back made 32 appearances for Nice in all competitions last season, including 4 in the Europa League.
His performances defied his years and he has now attracted the attention of some of the biggest clubs in Europe.
'Sky Sports' reports that the player has a £36m release clause in his contract. The same source reports that Arsenal tried to sign the player before he signed a professional contract with his home-town club in November 2016.
The youngster scored the winner on his Nice debut last season in a 1-0 win over Rennes and has been tipped to go on to big things.
