Lyon are hoping to sign former Newcastle defender Jean-Alain Boumsong from Juventus on loan for the rest of the season.
The Ligue 1 leaders are short of defensive cover after Brazilian Cleber Anderson was ruled out for six months with a serious knee injury.
Les Gones certainly looked fragile on Sunday night as they crashed to a 3-0 defeat at relegation strugglers Lens.
Lyon president Jean-Michel Aulas is now hoping to lure the France international back to his homeland during the January transfer window.
He told the club's television channel: "It is necessary for us to replace Cleber Anderson.
"We are in advanced talks with a French defender who plays for Juventus but as things are not yet signed we cannot confirm it.
"We hope that the business is concluded quickly, ideally at the start of this week."
