The FA have launched an investigation to uncover the culprits behind bugging the England camp last week.
The Daily Mail says lawyers have already been instructed to prevent the illegal tape from being published.
England were left facing yet more potential disruption to their World Cup plans when it emerged that a six-hour recording of team meetings was in existence.
Last night, FA officials still had no knowledge of who committed what amounts to a serious breach of privacy laws - or the contents of the tape.
Speculation remains that the sensitive tape includes Capello discussing tactics with his staff, as well as players talking about private matters that could cause some embarrassment to members of Capello's first team, as well as World Cup bonuses.
