Marciniak was the referee for last year's Champions League final between Manchester City and Inter Milan, and is regarded as one of the continent's finest officials, having been a FIFA-listed official for the last 12 years.
The 42-year-old, who primarily officiates in the Polish PKO Bank Polski Ekstraklasa, was included on the UEFA Elite referee list in 2015 and took charge of his first Champions League fixture the following year.
He is a regular at major international tournaments too, having featured at EURO 2016 and both the 2018 and 2022 World Cups.
He was appointed to referee the World Cup final between Argentina and France last year in Qatar, meaning he became only the second referee ever to take charge of a Champions League final and World Cup final in the same campaign.
