World Cup final referee Marciniak to officiate Champions League final
Marciniak, 42, became the first Polish referee to officiate a World Cup final when he took charge of Argentina's penalty shootout victory over France in Doha and was praised for his handling of the contest.
The Champions League final, which will be held in Istanbul on June 10th, will have the same team of on-field officials as the World Cup final, with Marciniak once again being assisted by compatriots Pawel Sokolnicki and Tomasz Listkiewicz.
Marciniak has refereed eight Champions League matches this season, including City's 4-0 win over Real Madrid in the semi-final second leg and Inter's goalless draw at Porto in the last 16.
He will take charge of his first Champions League final, having served as fourth official in the 2018 edition when Real beat Liverpool.
