French teams are limited to four players without EU citizenship. Hence, the squad list includes only the principal nationality of each player; several non-European players on the squad have dual citizenship with an EU country. Also, players from the ACP countries—countries in Africa, the Caribbean, and the Pacific that are signatories to the Cotonou Agreement—are not counted against non-EU quotas due to the Kolpak ruling.
