United resorted to spy tactics
Manchester United were so paranoid about in-house security and confidentiality in the 1990s that experts were brought in to search for bugging devices in their own boardroom.
Michael 'Ned' Kelly, the club's former head of security, has also revealed in his book Manchester United: The Untold Story how Alex Ferguson used a task force of SAS soldiers to monitor his own players and potential signings.
"When I first started at United, I was in charge only of match-day security," said Kelly.
"But the job grew and turned into a monster. By the end, I was doing all sorts of things, including debugging homes, phones and cars, even breaking up orgies."
