He played twice with the first team in his first season, then 11 times in the 2003–04 campaign as all goalkeepers (himself, Germán Burgos and Sergio Aragoneses) appeared in roughly the same matches[1][2] and they eventually qualified for the UEFA Intertoto Cup.
In mid-July 2010, after helping Alcorcón promote for the first time in its history to the second division – he was also in goal for the club's historical elimination of Real Madrid in the Copa del Rey – the 30-year-old Juanma moved abroad, joining a host of compatriots at Aris Thessaloniki F.C.
[7] Juanma only managed the club on two matches, as the competition was suspended due to the COVID-19 pandemic, and joined Albacete Balompié's staff in December 2020, as an assistant of Alejandro Menéndez.
Juanma announced his departure from Mérida on 29 May 2023, after promoting the club to Primera Federación and leading them to a comfortable 8th place finish.
[8] On 27 September, he was named manager of CD Atlético Baleares, replacing the sacked Tato,[9] but was himself dismissed on 12 March 2024.
