Born in Mazarrón, 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.
