I wondered what the crowd would be like for Hungary so briefly looked at the replay of the Hungary quarterfinal game. It appeared to be in the same arena and precede USA-Spain. I don't know if it is social distancing or lack of interest, but I don't think the crowd should be an issue. It will be the most hostile crowd, but not packed to the rafters or anything.
