FIFA has confirmed that Szymon Marciniak will referee Sunday's World Cup final between Argentina and France.

Marciniak has already overseen games involving both finalists in Qatar, taking charge of France's 2-1 group-stage win over Denmark and Argentina's last-16 victory by the same score against Australia.

The Polish official, who also refereed games at the 2018 World Cup in Russia, has shown just five yellow cards across his two fixtures at this year's tournament and is yet to give a single penalty or red card.

Some referees have attracted criticism for their displays in the World Cup's knockout stages, including Antonio Mateu Lahoz, who booked 15 players in Argentina's quarter-final win against the Netherlands.

The Moroccan Football Federation has lodged a complaint to FIFA regarding Cesar Ramos' performance as referee during their World Cup semi-final defeat to France on Wednesday.

FIFA also announced Qatar's Abdulrahman Al Jassim will officiate Saturday's third-place playoff between Croatia and Morocco.
