Daniel Siebert will take charge of the UEFA Champions League final between Paris Saint-Germain and Arsenal in Budapest on Saturday evening, the biggest appointment of his career and his first UEFA competition final.

The 42-year-old German will walk into the game after already handling nine Champions League matches this season, the most of any referee, and the final will be his 10th in 2025/26. For readers tracking UCL fixtures, it is the clearest sign yet that UEFA has put its trust in a referee who has become one of the busiest names on the circuit this year.

Siebert said the call came while he was at home with his wife, listening on loudspeaker as Roberto Rosetti, UEFA's refereeing director, delivered the news. He described it as a warm and emotional moment, and said he felt he had enjoyed a strong season. That trust did not come out of nowhere: he began refereeing at 14, joined the international list in 2015 and has already worked three matches at UEFA EURO 2020 and two more at UEFA EURO 2024.

What makes the appointment more striking is that it arrived after a calf injury partway through the season briefly put his availability in doubt. Siebert also had only one knockout match before the final, Bodø/Glimt against Inter in February, so UEFA has turned to him for the competition's most visible stage despite the disrupted run-up.

Siebert, who is a qualified teacher but no longer active in the classroom, said he is enjoying life as a professional referee and father to his two children, though he has left open the possibility of returning to teaching one day. For now, the biggest night of his career is in front of him, and in Budapest the final judgment will rest with a referee who has spent years moving toward this assignment.
