Lille boss Christophe Galtier has suggested that midfielder Boubakary Soumare is unhappy at the Ligue 1 outfit.
The 20-year-old now finds himself out of the starting lineup, leading to Galtier hinting that off-the-field matters are to blame for his omission.
Galter told L'Equipe: "There is a situation at the club that I do not comment on. In seasons, there can be tension between a player and his club. We'll settle this internally and find a solution.
Lille are looking to recoup in excess of £40m for the France Under-21 international.
