Subsequently, Merino went on to work extensively as a manager with the former club (although his first head coach experience arrived with precisely the latter).
Born in La Línea de la Concepción, Province of Cádiz, Merino joined Real Betis's first team in 1990, becoming club captain in later years. Out of his twelve years at the club eight were in La Liga, and he appeared in 203 games in that division, scoring two goals and surpassing overall 300 appearances; in the 1996–97 season, he contributed with 36 matches as Betis finished fourth.
In 2002–03, staying in Andalusia, Merino joined Recreativo de Huelva. In his first season the club was relegated, regaining top flight status in 2006. After featuring in 23 games in the 2006–07 campaign he retired from football, with more than 500 official matches played – both major divisions combined.
In the 2010–11 season, Merino cut ties with Betis and returned to Recre as assistant to Pablo Alfaro – a former Sevilla FC defender – with the club in the second division. In mid-October, after only eight games (four draws and four losses), Alfaro was sacked but he stayed with his successor Carlos Ríos, in the same predicament.
