On 7 January 2015, Duarte made his first-team debut, playing the full 90 minutes in a 1–2 away loss against Valencia CF for the season's Copa del Rey. His maiden La Liga appearance occurred on 8 February, against the same opponent and with the same scoreline, but at the Estadi Cornellà-El Prat.
Duarte renewed his contract with the Catalans on 11 June 2015, signing until 2019 and being definitely promoted to the main squad. On 29 May 2017, after falling down the pecking order, he agreed to a three-year deal at fellow league club Deportivo Alavés.
