Niels Nkounkou

Everton Nkounkou joined Everton on a free transfer in July 2020, signing a three-year deal, after rejecting a professional contract from Marseille due to the sporting plan proposed by the French club wasn't convincing for the defender and his future development. The opportunity of working under Carlo Ancelotti convinced Nkounkou to join the Toffees. Nkounkou's agent Yvan Le Mée stressed that Ancelotti called the player, spoke to him, and knew the player's potential. By working with the player, Ancelotti can make him a top player.

Nkounkou made his professional debut for Everton in a 3–0 EFL Cup victory against Salford City in which he impressed immensely, forming an effective attacking partnership down the left hand side of the pitch with fellow youngster Anthony Gordon. He put in another positive display in his second match, also in the EFL Cup, against Fleetwood Town which he capped with a back-heeled assist to set up a goal for Moise Kean in a 5–2 victory.

Nkounkou played his first league game for Everton on 1 November 2020 against Newcastle United, a game Everton lost 2–1. He replaced teammate Lucas Digne who was serving a one match ban. He made his second league appearance in the last day of the season when Everton suffered a 5–0 defeat to Manchester City on 23 May 2021.

Saint-Étienne In January 2023, Nkounkou signed for Ligue 2 club Saint-Étienne on loan. The deal was eventually made permanent.

Eintracht Frankfurt On 1 September 2023, Nkounkou signed a five-year contract with Bundesliga club Eintracht Frankfurt. He scored on his debut for the club, coming off the bench to net an 87th minute equaliser in a 1–1 draw vs Koln.

Loan to Torino On 1 September 2025, Nkounkou moved on loan to Torino in Italy, with an option to buy and a conditional obligation to buy.

International career Born in France, Nkounkou is of Republic of Congo descent. He has represented France and has been capped twice for the country's U19 side. In July 2021, Nkounkou received a call up to the France Olympics squad, who will face Japan, South Africa and Mexico in Group A of the tournament. He subsequently made his debut for France U23 when they played South Africa in the second tournament match on 25 July 2021.

Style of play Upon the signing of Nkounkou, Everton Director of Football Marcel Brands said "Niels is a young, talented player with good technical and physical skills." Jeremy Smith, a French football writer and podcaster at French Football Weekly, believed that “Nkounkou is a well-regarded young left-back who can also play further up the left flank is a little like a Benjamin Mendy in that he is strong, has a great engine and can patrol the whole flank all match and has a decent shot and cross on him too.” Championnat National 2
