Born in
A Coruña,
Galicia, Mosquera played
roller hockey for his high school team in neighbouring Santa María del Mar. In 2000, at the age of 12, he arrived in
Real Madrid's youth system. He started out as a professional in
2006–07's
Segunda División – four games, 84 minutes and relegation. On 24 January 2010, Mosquera was called to the first team for a match against
Málaga, but did not leave
the bench. He made his
La Liga debut two months and one day later, playing one minute in a 4–2 away win over
Getafe after replacing
Xabi Alonso. Mosquera signed precisely with Getafe on 12 July 2010, penning a five-year contract and reuniting with former Real Madrid Castilla coach
Míchel. He made his debut for the club 16 days later, scoring against Germany's
VfL Osnabrück in a
friendly. On 20 January 2012, after not playing one single minute under new manager
Luis García in
the season, Mosquera agreed to return to Castilla, with the side in the
Segunda División B. He scored his first goal in the
Spanish top tier on 14 September while at the service of the latter, contributing to a 3–2 away victory over
Rayo Vallecano. Mosquera cut ties with the
Valencians on 27 July 2015, and signed a four-year deal with
Deportivo de La Coruña hours later. He played 37 matches in his
first season, helping to a final 15th position in the table. On 2 August 2019, Mosquera terminated his contract at the
Estadio Riazor and joined
Huesca for two years the following day. During his spell in
Aragon, he totalled 100 appearances. On 8 July 2022, Mosquera moved to
Primera Federación club
Alcorcón. Two years later, the 36-year-old joined
Rayo Majadahonda of
Segunda Federación. ==Career statistics==
