Who is Ousmane Diabate

Born in September 2007, Ousmane Diabate is a highly rated 18-year-old Guinean defensive midfielder known for his physical presence, tactical awareness, and composure in central midfield.

Diabate began his career developing at Académie SOAR in Guinea, where his impressive performances caught the eye of European scouts.

He completed a transfer to Turkish Süper Lig side Gençlerbirliği in December 2025.

After rapidly rising through the club’s U19 ranks, he broke into the first-team squad, making eight senior appearances across domestic competition.

He further displayed his quality during Gençlerbirliği’s opening league fixture of the season, putting in a standout performance to help secure a 2-1 victory over Fenerbahçe.

His rapid rise at the club level earned him a call-up to the Guinea senior national team, making his international debut against Northern Ireland in June 2026.

However, Newcastle United moved decisively to win the race for his signature, securing one of West Africa’s brightest young midfield talents on a long-term contract.
