I’m not able to verify an exact total from the information I have here, so I can’t give a reliable number for all Marseille players who appeared in World Cup finals. The only clearly relevant confirmed item I found is that Quinten Timber is listed as a Marseille player in a 2026 World Cup squad source.

What I can confirm

  • Quinten Timber is identified as a Marseille player in a World Cup squad list.
  • Zinedine Zidane was born in Marseille and won the World Cup with France, but the source I found does not say he was a Marseille club player at the time of those finals.

Why the total is tricky

A correct total depends on the exact definition:

  • Marseille club players only.
  • Players born in Marseille.
  • Players who were at Marseille before, during, or after their World Cup finals appearances.

Those categories can produce different counts, so any single number without a full player-by-player check would be unreliable.

Best next step

If you want, I can help you build the exact count from a specific definition, such as:

  1. Marseille club players who appeared in World Cup finals.
  2. Players born in Marseille who appeared in World Cup finals.
  3. OM players by national team and tournament year.
