Trilli

Álvaro Pérez Campo (born 19 May 2003), commonly known as Trilli, is a Spanish footballer who plays as a right-back for Barcelona Atlètic.

Early career
Born in Ortigueira, A Coruña, Galicia, Trilli started his football career at Racing de Ferrol with his brothers, Raúl and Javi, where they played in the youth sector of the club. He signed for Deportivo de La Coruña's youth side in 2014 before eventually getting promoted to their Juvenil B side for the 2019–20 season. Trilli accumulated 5 appearances during that season but due to injury and COVID-19, his playing time remained restricted.

Deportivo La Coruña
Despite struggling to get playing time, Trilli was called up to Dépor's reserves in Tercera División, making his debut on 13 December 2020 by starting in a 2–1 away win over SD Fisterra. The following 6 August, he extended his contract until 2024 and was called up for the first-team after pre-season.

Trilli made his first-team debut on 29 August 2021, the first match of the 2021–22 Primera División RFEF, in a 5–0 victory over Celta de Vigo B. Within a week later, Trilli suffered a muscle injury in the iliopsoas of his left leg and was assumed to be out for 3 to 4 weeks, before returning to training in October.

Trilli only returned to action on 1 December 2021, when he started in a Copa del Rey tie against UCAM Murcia CF. From there, he made a further nine league appearances for the club before suffering from an anterior impingement in March 2022 that would leave him out for the rest of the season. As a result, Trilli had surgery performed on his ankle in June 2022 and returned to rehabilitation with the club's medical department in July 2022.

Following his return to fitness in August 2022 under Óscar Cano, Trilli was placed as a third-choice starter at right-back under Antoñito and Diego Villares, both of whom impressed during preseason in which Trilli was injured. During the season, his lack of playing time was contributed by continuous discomfort with the left leg,  Trilli finished the 2022–23 season with 11 league appearances and was announced by the club that he was departing in July 2023.

Barcelona
On 23 July 2023, Trilli signed a two-year deal with FC Barcelona after an agreement was reached with Deportivo.
