Dani Olmo stammt ursprünglich aus der renommierten Nachwuchsakademie des FC Barcelona. Von La Masia wechselte er aufgrund geringer Aussichten auf Spielzeit 2014 zum kroatischen Topklub Dinamo Zagreb.
Founded by a group of Swiss, German, English and Catalan footballers led by Joan Gamper, the club has become a symbol of Catalan culture and Catalanism, hence the motto "Més que un club" (More than a club).
He spent eight years of his career in La Liga, totalling 227 matches for Osasuna and Mallorca and scoring 47 goals (in Spain he also represented Leganés).
