Manuel Gräfe, a former referee and now head of the German refereeing body, disagreed. He challenged the notion that Davies's arm position was "unnatural".
"The arm had moved out slightly with the step even before the cross, but was still very much in a natural position, and when the cross was delivered, his arm was in a rather natural position, still relatively close to his body, and, crucially, the ball had bounced off his hip beforehand," Gräfe commented on X: "So the only argument in favour of a penalty is the previous movement of the arm outwards, but that happened before the cross was even struck."
In the end, though, Kompany's frustration over the two calls probably faded quickly. After PSG had briefly raced into a 5-2 lead, his side showed remarkable resolve, keeping the tie alive and pulling one back through Dayot Upamecano and Luis Diaz.
As a result, Munich's task for the return leg is less daunting than it briefly seemed. Kompany knew almost immediately after the final whistle what would be crucial on Wednesday, and the Belgian made a single, special request of the FC Bayern fans.
He urged the supporters to play their part in reaching the final in Budapest. "We need our fans and their support with the same passion as against Madrid," said the Belgian, before making a final, thoughtful request: "At home, my only request is this: if anyone has bought a ticket but isn't feeling well on match day, they should stay at home and give their ticket to the fittest people who can take that energy from the Allianz Arena with them. The 75,000 people in the Allianz Arena are important to us."
