Dagano began his career at Ivorian side Stella Club d'Adjamé, based in Abidjan. In 1999 he moved back to his homeland, with Etoile Filante, before making his move to Europe a year later, with Belgian side Germinal Beerschot. After an impressive season with Germinal, Dagano moved to Genk, where he won the Ebony Shoe, before spells in France, with Guingamp and FC Sochaux. In 2008, he joined Al-Khor. He later left Al Khor for Al Sailiya two years later, but the club was subsequently relegated despite Dagano's impressive goal scoring record.
