Lille have agreed a deal to sign Djibril Sidibe from Troyes for an undisclosed fee.
Sidibe, 19, had been linked with Lyon but Lille have won the race to clinch the defender's signature.
The Frenchman made 34 appearances for Troyes in Ligue 2 last season as the club achieved promotion to the top flight.
"L'ESTAC and Lille have reached an agreement for the transfer of Djibril Sidibe," read a statement on Troyes' official website.
"The young right-back also interested Lyon, but president [Daniel] Masoni has completed negotiations with LOSC, with the player having expressed a preference for Lille.
"Everyone at Troyes send their best wishes to Djibril for continued success for the remainder of his career."
