The Tunisia international will ply his trade in La Liga after securing a switch to the Ramon Sanchez-Pizjuan Stadium.
He will hope to help Quique Sanchez Flores's men move up from 17th in the table, as they currently sit only one place above the relegation zone. Former Red Adnan Januzaj is also on the club's books.
After joining our youth ranks from Monaco in 2019, the 20-year-old made his Premier League debut in the 2-1 win at Wolverhampton Wanderers, on the final day of the 2020/21 season, impressing with his blend of skill and tenacity.
A loan spell with Birmingham City in the Championship last term helped to further his experience.
