The youngster is one of the biggest promises of Ligue 1 football, and a quick look at his numbers shows why. He has played 27 matches this season and has started 23 of them. He even scored one goal and gave an assist, the first ones in the first team.
That's why important clubs like Real Madrid and PSG are following his progress. The problem is that he is only 17 years old and on a contract until 2022: his current team will want to protect him so as not to ruin what would be a tremendous future there.
Bild' claims that Borussia has been following him for years, but that the club had refrained from making a bid because he didn't have French nationality. FIFA rules dictate that you cannot hire children under 17 who do not have the nationality of the country in which they play, but that is no longer a problem.
The source also claims that the offer for the player is of no less than 50 million euros; this is an initial figure that is rising - its market value is 33.4 'kilos'.
