Martin Demichelis may be invisible at times but we don't think he qualifies as a ghost.
Manchester City midfielder Fabian Delph is adamant, though, that he has personally witnessed proof of the existence of supernatural beings.
In an unusual gear change during an interview with City's YouTube channel, the England international revealed that he sees ghosts "all the time".
Delph, who has seen his first season in Manchester limited due to injury, claims to have "genuinely" seen no fewer than four ghosts in his 26 years on this planet.
Perhaps he is just confused about the chorus of boos that can sometimes ring around the Etihad Stadium.
Check it out below (with Delph's spooky revelation coming at 5:20).
