After Fuentes took over as manager of Primera División club Universidad de Concepción, he signed De la Fuente.[4] He made 11 appearances in the 2015 Apertura and 9 in that season's Copa Chile, helping his team reach the semifinals, as well as appearing on the losing side in the 2015 Supercopa.[2][5] Although he played little in the Clausura, he established himself in the starting eleven the following season,[6] and his performances attracted attention from other clubs.[7][8] In early 2018, De la Fuente played in the Copa Libertadores for Universidad de Concepción against Vasco da Gama of Brazil: despite a 4–0 defeat in the first leg, he felt the tie was not over,[9] but, at 2–0 down in the return leg, he was sent off for kicking an opponent in the groin.[10]
He began to study law in the context of COVID-19 pandemic, but he had to suspend due to the fact that the university changed the course to in-person mode. So, he began to study at the INAF [es] (National Football Institute).[12]
