The 19-year-old full-back, who has been capped seven times by France Under-21s, also had the chance to speak with Lyon but he has his heart set on joining Les Dogues
The teenage defender, who will turn 20 later this month, had also been courted by Olympique Lyonnais but he is now poised to link up with Les Dogues.
"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."
Sidibe, who has been capped seven times by France's Under-21s, made 34 appearances in Ligue 2 last year, scoring one goal.
