Bernardo Cos

Cos began his football career with the youth sector of San Lorenzo de Córdoba at 12 years of age. He then made his senior debut for the club at 17 years of age in 1966, adorning the number 8 within the lower ranks of the club. However, he demonstrated enough talent that in between the 1969 and 1970 seasons, Belgrano expressed interest in signing the forward for their club and later found relative success at the 1971 Campeonato Nacional. Throughout the 1972 season, Spanish talent scout Juan Mascaró would express interest in Cos for him to play for either Barcelona or Málaga with this being a rare opportunity due to foreign players in European clubs still being a recent phenomenon. Despite being born in Argentina, he registered as a Paraguayan player for Barcelona for the 1972–73 season for $55,000. Arriving in the Catalan city with a tear in the right leg, despite initially considered fit for play by Doctor Moragas, he was injured once more in the club's first training session as his debut wouldn't be until six months later into the season. Nonetheless, he contributed to where the club ended as runners-up for the 1972–73 La Liga. He received the nickname "Cuchi" from a Catalonian newspaper in 1973 from ignorance and mockery of South American players that had arrived at Spain. The origin of this nicknamed stemmed from Cos' indigenous background and how the name was derived from the Sioux. At the time however, Cos took it as a part of Spanish humor. The following season 1973–74…

Cos later worked with his son at the Headquarters of the Provincial Bank of Córdoba. He remains an ardent supporter his former clubs of San Lorenzo de Córdoba and Barcelona.
