Tennis on football?

Bayern fans twice threw tennis balls at the pitch in protest - because of this, the cup match with Preussen was first postponed and then interrupted.

This is how Munich fans expressed their dissatisfaction with the holding of the German Super Cup in 2023 on August 12, when the rest of the German teams had already played their first round matches of the German Cup (and Bayern had to wait a month).

I definitely didn’t succeed in helping my club. Bayern won, but now must pay about 65 thousand euros in fines - €350 for each of the 185 balls thrown onto the field.
