Overview:

• Juan Kopriva is an Argentine footballer who has been registered as having played for Club Alianza Lima, one of Peru’s most prominent clubs based in Lima.
• Publicly available, widely documented information about Kopriva is limited. He is not among the most widely profiled Argentine exports or widely covered in major international football databases, so details such as exact birthdate, position, and full career history may be sparse in mainstream sources.

Typical next steps to find more detailed information:

• Search Peruvian sports news archives (El Comercio, Depor, La República) and Argentine local media for match coverage or transfer announcements mentioning Kopriva.
• Look up national and regional football databases (Transfermarkt, Soccerway, BDFA) which sometimes include lower-profile players or past squad registrations.
• Consult social media or fan forums dedicated to Alianza Lima; supporters often keep detailed records of past players and appearances.
