Nico González came to FC Barcelona’s youth football at 11 from Montañeros after the Barça coaches saw him play in a friendly play in Galicia. Since then, his progression has been spectacular. It is an interior with a marked Barça DNA, which began to shine with Marcel Sans’ Infantil B, which was proclaimed champion of the League in the 2013/14 season. He has gone through all the categories of Barça academy football and stands out, for example, his participation in winning the League titles with Cadet B (2015/16), Cadet A (2016/17 and 2017/18), and the Youth A (2019/20).

He made his Barça B debut at just 17 years of age under the guidance of Garcia Pimienta in the last match of the 2018/19 season at the Castellón pitch. In the 2019/20 season, he started all six UEFA Youth League games and was later called up for the play-off for promotion to Second Division A with the reserve team.

In 2021, Nico made his debut with the first team, with Ronald Koeman on the bench, in the first league game of the 2020/21 season, against Real Sociedad at the Camp Nou. After making great performances, his role increased, and he became a member of the first team in the winter of 2022, already with Xavi as a coach.
