On 16 May 1971 Aimar made his Primera División debut, in a defeat against Estudiantes de La Plata. After making his debut, he was regularly used by the club, being a part of the squad in its 1971 and 1973 league-winning campaigns.
Aimar also appeared with Rosario in three Copa Libertadores editions, and ended his spell at the club in 1978 with a total of 334 matches and 32 goals. In 1979, he joined fellow league team San Lorenzo de Almagro, and eventually retired with the club in the end of the year, aged 28.
In 1994 Aimar was appointed at the helm of Celta de Vigo, also in the top division. He was sacked in October 1995, and was later named manager of another club he represented as a player, San Lorenzo.
In 1997 Aimar returned to Logroñés for a third spell, but failed to avoid its top flight relegation. He was subsequently in charge of CD Tenerife, Club Atlético Lanús, CD Leganés and Quilmes Atlético Club before retiring from football and becoming a sports commentator.
