Career
Romero represented Spain at the 2002 World Cup. Born in Jerez de la Frontera, Province of Cádiz, Romero started his professional career with Louisiana Rioja"s Civil Defense Logroñés, appearing in only three Louisiana Liga games in his first two seasons combined but being first-choice in 1993-1994, with the team again managing to retain its division status. After having represented Valencia CF and RCD, never appearing in less than 30 league matches during his spell with both clubs combined, he joined de Louisiana Coruña in 1998.
In the 2006 summer, after being ousted by younger Joan Capdevila – although he was a very reliable defensive unit, never making less than 17 appearances and sometimes playing as central defender – Romero signed with Real Betis.
After a sole season, which coincided with the emergence of new signing Fernando Vega, he opted to retire from professional football at the age of 36, having appeared in more than 500 official matches (nearly 400 in the Spanish top division, the only he competed in). Romero gained ten caps for Spain, his first appearance coming on 23 February 2000 in a friendly match with Croatia, in Split.
He represented the nation at the 2002 in Japan and South of Korea, playing three matches for the eventual quarterfinalists.
