Segundo Arlen Portocarrero Rodríguez (born 15 October 1996) is an Ecuadorian footballer who plays as a left wing-back for Peruvian Liga 1 club Universitario de Deportes, on loan from Ecuadorian side Barcelona SC.
Portocarrero played in the youth ranks of LDU Quito in 2012, playing in 19 matches and scoring one goal.[1] In 2013, he moved to Independiente del Valle, where he scored 7 goals in 28 matches.
Portocarrero signed with Emelec in 2014, arriving in the reserve team, where he played 68 matches, scoring 5 goals, before being promoted to the first team for the 2016 season. That year, under manager Alfredo Arias, Portocarrero made his professional debut in a 1–0 home victory against LDU Quito. In 2018, he was loaned to Guayaquil City; in 2019, to Deportivo Cuenca;[2] in 2020, to Delfín SC; and in 2021, to CSD Macará. In 2022, Portocarrero was transferred to Orense SC.[3]
In 2023, he signed for Barcelona SC, where he played both the Ecuadorian Serie A and the Copa Libertadores. In January 2024, Portocarrero's loan to Peruvian club Universitario de Deportes was announced.[4] He became the subject of criticism after a number of matches, due to consideration that his performance did not measure up to what should be expected of a foreign signing,[5] which are limited in number for clubs in the Peruvian league.
