Niels Nkounkou has received two concrete inquiries from abroad, including a club from his home country, France. He joined Eintracht Frankfurt from St. Etienne in 2023 and played twelve league matches and eight in the Europa League last season.

Niels Nkounkou might leave Eintracht Frankfurt prematurely in January due to stagnating development. Despite having a contract until 2028, he is considered a departure candidate because his playtime in the Bundesliga has significantly decreased since October. Summer signings Nathaniel Brown, Rasmus Kristensen, and Arthur Theate have surpassed him in the squad hierarchy.
