R9, meaning Ronaldo Nazário, is generally credited with 0 own goals in major career stat summaries. The query results I found mainly point to Cristiano Ronaldo own-goal discussions, while R9’s career goal totals are listed separately and do not show any own goals.

Context

  • R9 is the common nickname for Ronaldo Nazário , the Brazilian striker.
  • Public stat pages focused on his career goals do not list any own goals.
  • Some search results were about Cristiano Ronaldo , which is a different player and not relevant to R9.

Short answer

  • Own goals by R9: 0 based on the available career stat summaries.

Note

There is some online noise around this topic because “Ronaldo” can refer to more than one player, but the R9 records I found do not show an own-goal tally.
