Born in Puerto Serrano, Cádiz, Andalusia,[2] Luismi graduated from Sevilla FC's youth setup, making his debut as a senior with the C side in the Tercera División.

[3] On 11 November 2012, Luismi broke two bones in his skull in the dying minutes of a 1–0 home win over Real Jaén,[4] only returning to action on 31 March of the following year, against the same club.

[5] On 1 February 2014, he was called up by manager Unai Emery for a La Liga match against Málaga CF as a replacement for Cardiff City-bound Cala,[6] also being selected to the game against UD Almería on 8 March[7] but remaining on the bench on both occasions.

Luismi penned a new two-year deal with the Andalusians on 3 July 2014,[8] being also an unused substitute in the 2014 UEFA Super Cup 2–0 loss to Real Madrid at Cardiff City Stadium on 12 August.

[11] The jersey, worn by Antonio Puerta when he died playing for Sevilla in 2007, was only to be given to products of the club's academy from that moment onwards;[12] halfway through the campaign, however, he was stripped of the number when it was controversially handed to Argentine Federico Fazio.
