What bubble burst out of interest?
You've got your theory and I’ve got the factual answer, in Poland, this wasn’t the biggest night in world speedway. Poland doesn’t care about ‘World’ speedway, same they don’t care about British, Swedish or Danish. Ekstraliga final was bigger than this to them, and so was Vojens GP final. They have small interest in SoN.
Out of curiosity, why does everyone think it’s a joke that Polish fans didn’t fill the stadium, it was £40-90 for one ticket. I’ve been to Ekstraliga matches for £7. Also, Poland wasn’t the only team racing, where were the masses of Swedish, British, Danish, Australian, Czech fans? And before you say “it was in Poland” the FIFA world cup is all over the world but millions of other nations travel to different countries to watch it.
