Ricardo Ismael Rojas Mendoza (born 26 January 1971) is a retired Paraguayan professional footballer who played as a full-back.
Born in Posadas, at the Argentine province of Misiones, Rojas played for Argentinos Juniors at the same time as Christian Dollberg in 1991.
In July 1999, the 28-year-old moved abroad and joined Benfica, alongside his teammate, Carlos Bossio;in what he labelled the transfer as the highest point in his career.
[6][7] However, in 2000–01, the signings of Ivan Dudić on the right, and the breakthrough of Diogo Luís on the left, severely diminished his playing time,[8][9] so in February 2001, he was loaned to River Plate.
[12] In 2001–02, already with Ramón Díaz in charge, Rojas alternated with Matías Lequi on the left and despite speculation that he would be released, he signed on permanent deal in early 2002.
