It is a challenge for sports leagues across the world – if play can only resume in empty stadiums, how can the atmosphere be improved?
However, not many clubs will be rushing to follow the example of FC Seoul.
The top-flight South Korean side has apologized after fans accused them of using sex dolls in the stands.
FC Seoul insisted they were “premium mannequins” rather than sex dolls – but did admit they came from a supplier that produces sex toys.
And some of the dolls were holding signs advertising sex websites – despite pornography being banned in South Korea.
