The agreement includes £5 million in potential add-ons, making the total value of the move £31 million. Ait-Nouri has been on Manchester City's radar as they look to strengthen their left-back options ahead of the new season.
Pep Guardiola's team must complete the transfer before 10 June to ensure Ait-Nouri's eligibility for the Club World Cup group stage.
Manchester City's left-back position has been vacant since Benjamin Mendy's last appearance in August 2021. Ait-Nouri's impressive performance last season, where he recorded more goal involvements (11) than any other Premier League defender, highlights his ability to contribute to the team's attack from the back.
