At La Sportiva, he stood out for his goalscoring ability, which eventually drew the attention of Sporting de Gijón, who signed him in 1910.

[3] In the first-ever Asturian derby between Sporting de Gijón and Real Oviedo (named Real Club Deportivo Oviedo at the time) held on 25 January 1920, it was Fernando who scored the opening goals, thus netting the first goal of one of Spain's biggest rivalries.

He also served as a referee in the first-ever game of the Asturias national team on 4 June 1922, which ended in a 3–7 loss to St Mirren F.C.

[citation needed] In 1917, he was summoned to play for the Cantabric national team, a side consisting of players from the provinces of Asturias and Cantabria.

He and his brother Senén, were a member of the team that participated in the 1917 and 1918 editions of the Prince of Asturias Cup, an inter-regional competition organized by the RFEF.
