Adli signed for Milan from Bordeaux in 2021 and was loaned back to the French side until 2022. After failing to establish himself at the San Siro side during the 2022-23 and 2023-24 seasons, he spent last term at Fiorentina, where he scored five goals and provided seven assists in all competitions. Upon returning, Milan coach Massimiliano Allegri deemed him surplus to requirements and left him out of the squad for the current campaign.
