Niels Nkounkou is a French left-back, born on 1 November 2000 (age 25), and now with Eintracht Frankfurt. His best league return came at Saint-Etienne in 2022-23, when he scored six goals in 20 appearances – useful output from a position where end product is often treated as a bonus rather than a requirement.
That Saint-Etienne spell remains the neatest snapshot of his career so far: athletic, forward-minded, and capable of making a measurable contribution in the final third. He then moved on to Eintracht Frankfurt, where he has continued as a left-sided defensive option.
Nkounkou was linked with a move to Celtic in August 2026. At this stage, his career is that of an established professional still in his mid-twenties, with Saint-Etienne providing his strongest attacking season and Frankfurt his current platform.
