On 7 October 2013 Kadri was appointed as manager of Saudi club
Al-Nahda. On 30 April 2014, Kadri was appointed as manager of newly promoted
Saudi Pro League club
Al-Khaleej. He left the club at the end of his contract following the conclusion of the 2015–16 season. He returned to the club on 30 August 2016 following the sacking of
Patrick De Wilde. On 31 January 2021, Kadri was appointed as manager of Saudi club
Al-Adalah. In June 2021, Kadri became assistant coach of the
Tunisia national team for the second time. This time under
Mondher Kebaier, with whom he accompanied the team to the
2021 Africa Cup of Nations, where he became head coach in the round of 16 after Kebaier contracted
COVID-19. On 23 January 2022, during the match against
Nigeria in the round of 16 of the 2021 African Cup of Nations, Kadri replaced the first coach, Mondher Kebaier, at the helm of the team due to his
COVID-19 infection, the match ending with a victory for Tunisia 1–0. On 30 January he was appointed temporary coach after being eliminated from the quarter-finals of the Africon against
Burkina Faso. In the process, he led the team to qualify for the
2022 FIFA World Cup, allowing him to become a permanent coach of the senior side. In the 2022 FIFA World Cup, Kadri's Tunisia once again failed to live up to expectation as Tunisia failed to advance past the group stage due to the 1–0 defeat to
Australia in the World Cup
group D, despite Tunisia's 1–0 win over defending champions
France in the final match. After the cup, Kadri was allowed to remain in charge of Tunisia until 2024. On 24 January 2024, Kadri resigned from his position after the
2023 Africa Cup of Nations group stage exit. On 14 April 2025, Kadri was appointed as manager of Saudi club
