Ousmane Diao (born 8 June 2004) is a Senegalese professional footballer who plays as a centre-back for Danish Superliga club FC Midtjylland.
Diao was born and raised in Ouakam, a commune in the capital Dakar, where he also started his career in AS Ouakam. In 2019 Diao moved to the football academy Darou Salam - Académie Foot Darou Salam de Dakar - where during his time at the academy he was also selected for the Senegal U-20 national team.
In August 2022, Diao reportedly signed with Danish club FC Midtjylland. However, Midtjylland never officially confirmed this themselves. In January 2023, Portuguese club C.D. Mafra confirmed that Diao had signed with the club. Several sources - although neither Mafra nor Midtjylland confirmed this - wrote that Diao joined Mafra on a loan deal from Midtjylland, until summer 2024.
In the summer of 2023, Diao was back in Midtjylland and also took part in a training match for the club. He then returned to Mafra, where he became a huge profile for the club in the 2023âÂÂ24 season. His good performances for Mafra made Diao attract a lot of interest, including from Sporting CP, who according to sources were close signing Diao. On 27 June 2024, FC Midtjylland confirmed that Diao had been brought to the club on a contract until June 2029.
