Manuel Castellano Castro (born 27 March 1989), commonly known as Lillo, is a Spanish footballer who plays as a full-back for Primera Federación club San Fernando.

Born in Aspe, Alicante, Valencian Community, Lillo began his career with local Valencia CF, playing three seasons with the reserves. In 2006–07 and 2009–10, he totalled 23 appearances, with the team being relegated from Segunda División B on both occasions. In between, he spent the 2008–09 campaign on loan at Real Murcia, playing less than one third of the games as the club finished 14th in the Segunda División.

On 21 March 2010, Lillo appeared in his first official match with the main squad, playing the first 45 minutes of a 2–0 La Liga home win against UD Almería.^[2] In late May, as his contract with the Che was expiring, he signed with Elche CF;^[3] however, due to a mistake from his agent, the move was declared void and, two months later, he joined Almería.^[4]

Lillo spent the vast majority of his first season with the Andalusians with the B side in division three, appearing in only two games with the first team. In November 2012, the free agent joined another club in that tier, CD Alcoyano.^[5]

On 18 July 2013, Lillo moved to SD Eibar, recently promoted to the second division.^[6] He played 26 matches in his debut campaign, with the Armeros being promoted to the top flight for the first time ever, and on 11 July 2014 renewed his link for a further year.^[7]

Lillo agreed to an extension at the Basque club on 31 December 2014, until 2017.^[8] On 5 July 2016, he mutually agreed to terminate his contract,^[9] and signed a two-year deal with Sporting de Gijón just hours later.^[10]

On 1 September 2017, free agent Lillo agreed to a two-year contract with CA Osasuna in the second division.^[11]
