In his fourth match with the club, on 29 April 1979, he scored against Barcelona at Camp Nou, putting one past Pedro Artola albeit during a 2–1 defeat.[2][3] Three weeks later, he scored Espanyol's 2,000th top-flight goal in a victory over Burgos.[2] The transfer of young star defender Canito to Barcelona meant Aifuch became a regular starter during his second season in 1979–80.[1] He netted his only brace with the team in a win over Las Palmas in May 1981. However, Canito's return to Espanyol in 1981–82 relegated him back to the bench. Even further, he suffered a grave injury during a match against Las Palmas on 10 November 1981, tearing his MCL in his left knee. This was Aifuch's last match in La Liga.[2]
He returned to Cerro Porteño for a season before finishing his career with Sportivo San Lorenzo and Sportivo Iteño, with a short stint with Italian club AC Santa Maria in 1984–1985.[2]
In 2017, he was selected by a commission of Cerro Porteño fans as one of the 35 "club idols" that received a tribute at the re-inauguration of their home ground Estadio General Pablo Rojas.[4]
His uncle, Juvencio Osorio, won three straight titles with Cerro Porteño (1972–1974) before spending four years at Espanyol and eventually retiring with Cerro Porteño.[3] They were teammates for one season in Spain in 1978–79.
