Born in Mazarrón, Region of Murcia, Alcalá was a product of Málaga CF's youth ranks. He appeared once for the first team in the 2006–07 season, with the Andalusians in the second division; subsequently, he spent two years on loan in the third level, with AD Alcorcón and UD Marbella.
In late August 2009, another season-long loan was arranged as Alcalá joined freshly promoted Real Unión. After being relegated from division two and having appeared in less than half of the league's matches, his contract with Málaga expired and was not renewed, so the player was released; soon afterwards, he moved to Getafe CF's reserves in the third tier.
On 30 August 2015, Alcalá moved to fellow league team Girona FC after agreeing to a four-year deal. He was an undisputed starter during the following campaigns, achieving promotion to La Liga in 2017.
Alcalá made his debut in the top level on 19 August 2017, starting in a 2–2 home draw against Atlético Madrid. He scored his first goal in the competition seven days later, netting the game's only in a home success over Málaga CF.
