Sandro Schärer to Referee PSG vs Bayern Munich in Champions League Semi-Finals – Key Preview & Odds

Swiss referee Sandro Schärer has been appointed to officiate the UEFA Champions League semi-final first leg between Paris Saint-Germain and Bayern Munich at Parc des Princes on Tuesday evening, April 28, 2026. The match, scheduled for 21:00 CET, will mark Schärer’s second appearance in a high-stakes European fixture this season, following his role in the Europa League quarter-final between Bologna and Aston Villa. Earlier in April, the 37-year-old from Schwyz received a call-up for Switzerland’s squad at the upcoming FIFA World Cup in the United States. Schärer previously officiated PSG’s 4-0 victory over Atalanta in the league phase of this season’s Champions League, giving the French side familiarity with his refereeing style. His appointment continues a rare milestone for Swiss officials in elite European competition, as Massimo Busacca was the last Swiss referee to seize charge of a Champions League semi-final — Lyon versus Bayern Munich in 2010. The Swiss referee gained wider recognition in March 2025 after managing the Lille versus Borussia Dortmund round-of-16 clash, a match that drew criticism from Lille president Olivier Létang over alleged bias. Létang had questioned Schärer’s conduct, particularly noting communication with Dortmund players in German during halftime, though no disciplinary action followed from UEFA. Bayern Munich advanced to the semi-finals by eliminating Real Madrid, while Paris Saint-Germain reached this stage after defeating Liverpool in the quarter-finals. The winner of the tie will progress to the Champions League final, set for June 1, 2026, at Wembley Stadium in London.
