Polish referee Szymon Marciniak will take charge of Sunday's World Cup final between France and Argentina, FIFA announced on Thursday.
The 41-year-old has already officiated matches involving both teams at the tournament - Argentina's last-16 win over Australia and France's group-stage victory against Denmark.
Marciniak's assistants in Sunday's match will be compatriots Pawel Sokolnicki and Tomasz Listkiewicz.
The three have already overseen matches at the Under-18 world championships as well as the Euros in 2016.
