Football fans are used to not believing their eyes as they watch what is happening on the pitch.
But crowds in Bolivia have been spooked by a ghostly figure running through the crowd during a match.
The shadowy figure glided through the stand during a game in Hernando Siles Stadium in La Paz, Bolivia, on Thursday night – and even appeared to run straight through a barrier .
The spectre was captured by tv cameras and has now gone viral.
How do you think, what can it be?
