Sergio Alejandro Díaz (born 9 February 1985) is a Spanish retired footballer who played as a central defender.
Díaz was born in Turón, Asturias. After starting out at local Real Oviedo, making his senior debut aged 17 in the Segunda División in a relegation-ending season, he finished his football development at Real Madrid, having joined in 2003.[1]
Over two seasons in the second division – of the five in total he spent with the team[2] – Díaz made a further seven league appearances with the reserves. He was also called up to the first team for a UEFA Champions League match against FC Dynamo Kyiv in December 2006 (the group stage's last), but remained an unused substitute;[3] he earned another call that month, in La Liga against Sevilla FC, although he ultimately was cut from the final squad of 18.[4]
For the 2008–09 campaign, Díaz signed with Hércules CF, who was coached by his former Castilla manager Juan Carlos Mandiá. He appeared very rarely for the fourth-placed team in division two, following a severe injury contracted in preseason.[5]
Díaz moved to Gimnàstic de Tarragona in 2010–11, agreeing to a three-year deal with the second tier side. On 29 July 2011, however, he terminated his contract with the Catalans,[6] and returned to old club Hércules the same day.[7]
