"Manchester United team photos
On 18 April 2001, Power strolled onto the pitch, in team colours, and took up a position next to player Andy Cole. Without any complaint the team photo was taken before Manchester United's Champions League match against Bayern Munich. It was not noticed until after the match that there was an unknown "player" in the picture."
