Nico González arrived at FC Barcelona at the age of 11 from Montañeros, after Barça scouts had seen him play in a friendly in Galicia. His progress since then has been spectacular. He began to shine in the Under-14s B team which were proclaimed league champions in the 2013/14 season, also winning titles for the club in 2015/16, 2016/17, 2017/18 and 2019/20 as he made his way up the ranks.
González made his debut for Barça B at just 17 years old, in the last game of the 2018/19 season, in Castellón. The 2019/20 season saw him start in six UEFA Youth League matches and be called up for the promotion playoffs squad for Barça B. He played 18 league games for the Under-19s, in which he scored three goals.
González is notable for his vision and reading of the game, his skill in possession and his vision and tactical nous. He can also play in the centre of the midfield.
