After playing for modest clubs in his country he arrived in Spain at the age of 23, purchased by Atlético Madrid, but appeared very rarely for the Colchoneros, being often demoted to its reserves and also being loaned twice, notably to CP Mérida which he helped promote from the second division by scoring a team-best ten goals in only five months.
Released by Atlético in the 1995 summer, Benítez signed with fellow La Liga side RCD Espanyol, going on to experience his best years: alternating between the starting XI and the bench, he amassed 166 competitive appearances for the Catalans, helping them to the 2000 conquest of the Copa del Rey.
Benítez started his coaching career in 2008, taking charge of lowly Club Silvio Pettirossi as it was experiencing its first season in the Primera División – short-lived, as the side dropped down two tiers in as many years.
He was selected for the 1998 FIFA World Cup, playing in all four matches as the country reached the round-of-16 and netting in the 3–1 group stage win over Nigeria.
