Oussama Haddadi has signed a one-year contract with Saudi Professional League side Al Ettifaq, moving from French Ligue 1 club Dijon.
In January 2017, the defender joined the Mustards from Club Africain and went on to make 78 league appearances, scoring three goals.
Last season, the 27-year-old made 32 appearances and scored twice as Dijon ended the season in the 18th spot on the table.
The Mustards will play Ligue 2 side RC Lens in the relegation play-offs for a chance to remain in the French top-flight.
Haddadi has 14 caps for Tunisia and will hope to make Alain Giresse’s squad to the 2019 Africa Cup of Nations in Egypt, billed for June and July.
