Sergio Aguza Santiago (born 2 September 1992) is a Spanish footballer who plays as a midfielder for Fuenlabrada.
Born in Sant Boi de Llobregat, Barcelona, Catalonia, after playing youth football with CF Gavà's youth setup EF Gavà and UD Cornellà, Aguza joined Real Madrid's youth facilities in 2008, aged 16. In 2011–12 season Aguza made his senior debut, playing for the C-team in the Tercera División.
In July 2013, he was promoted to the reserves in the Segunda División.[1]
On 8 September Aguza made his professional debut, starting in a 0–1 home loss against CD Mirandés.[2] He scored his first goal on 15 February of the following year, netting his side's second in a 3–1 home success against FC Barcelona B.[3]
On 31 July 2015, Aguza signed for English Football League Championship side Milton Keynes Dons on a two-year deal.[4] Aguza made his debut for the club on 11 August 2015 in the 2–1 Football League Cup win over Leyton Orient.[5]
On 16 January 2016, following limited appearances for the club, Milton Keynes Dons announced that Aguza had left the club via mutual consent.[6]
On 18 January 2016, Aguza signed a two-and-a-half-year contract with SD Ponferradina, returning to Spain and its second level.[7] He scored his first goal for the club on 20 March, in a 2–1 home win against SD Huesca, and added two more match-winners against CD Lugo and Albacete Balompié; at the end of the campaign, he suffered team relegation.
On 7 July 2016, Aguza signed a one-year deal with AD Alcorcón also in the second level.[8] The following 31 January he rescinded his contract,[9] and signed a six-month deal with fellow league team Córdoba CF just hours later.[10]
On 13 July 2018, Aguza signed a two-year contract with UD Almería, still in the second division.[11] On 11 March 2020, he renewed his contract until 2023.[12]
On 5 October 2020, Aguza joined FC Cartagena, newly-promoted to division two, on a one-year loan deal.[13] The following 13 January, however, his loan was cut short,[14] and he moved to fellow league team Ponferradina also in a temporary deal nine days later.[15]
On 13 August 2024, Aguza signed one-season contract with Fuenlabrada in the third tier.[16]
