Born in Madrid, Mata finished his youth career with local Galáctico Pegaso, making his senior debut with the reserves in 2007. After appearing with the main squad in Tercera División, he moved to neighbouring Rayo Vallecano in December 2009, being immediately loaned to UD Socuéllamos in the same level.[2][3]
On 5 July 2012, Mata signed for Lleida Esportiu also in the third division.[5]
Girona
After scoring 32 goals over two seasons, Mata moved to Segunda División after agreeing to a two-year deal with Girona FC on 18 June 2014.[6] He played his first match as a professional on 24 August 2014, starting in a 1–0 home win against Racing de Santander.[7] He scored his first goal six days later, the winner in a 2–1 away victory over AD Alcorcón.[8]
On 2 July 2018, Mata signed a three-year contract with La Liga club Getafe CF as a free agent,[14] making his debut in the competition on 24 August at the age of 29 years and ten months in a 2–0 home win against SD Eibar where he played 79 minutes.[15] He scored his first top-flight goal on 1 October 2018, the equaliser in a 1–1 away draw with RC Celta de Vigo.[16]
In the following year, Mata scored braces against Deportivo Alavés, Celta and SD Huesca, being also named the competition's best player for the month of February.[17] On 17 October 2020, he scored a penalty in a 1–0 victory over FC Barcelona, the club's first against that opponent since 2011.[18] He totalled 14 league goals in his first season[19] and 11 in the second,[20] but featured more often than not as a winger in his later years; after manager José Bordalás' departure in May 2021 and until his return in April 2023, he struggled to get playing time.[21]
Later career
On 27 June 2024, the 35-year-old Mata signed a one-year contract with UD Las Palmas also in the top tier.[22]
