Following the pyro show by Bayern fans last night, Herbert Hainer said about a potential punishment by UEFA: “If UEFA is passionate about football, which I assume they are, they will let it pass today”

However, according to @BILD, yesterday's events will not pass. There will definitely be a report of the events in the official match report, which will be sent to the UEFA Disciplinary committee today. The committee would then launch an investigation. It remains to be seen how UEFA will react and whether there will be another ban on Bayern fans in the semifinal
