The Champions League semi-final between Paris Saint-Germain and Bayern Munich on Tuesday was defined less by goals than by two non-calls for handball. The match official twice declined to award a penalty against Bayern after the ball struck a defender’s arm inside the area, rulings that CBS Sports reported as controversial given the match’s importance. The decisions illustrate a persistent tension in UEFA’s handball interpretation: the distinction between a natural and an unnatural arm position remains subjective even after recent rule revisions. With the tie still open ahead of the second leg, the lack of a definitive standard leaves room for further debate and potential influence on the aggregate score.
