Hmm, just to set the record straight AND AS A WARNING TO YOU GUYS.
They didn't actually tap/bug anyone's phones. They just realised that people don't tend to change the default pin on their voicemail accounts. So they worked out what the voicemail number for the people in question were, dialled that number, tried the default PIN and bingo!!
And to keep this on topic. I would welcome WGS back in a blink. The Saints team he managed were the fittest I have seen for a long time, and he didn't take any **** from the players either.
