Neil Lennon has admitted the incredible lengths Celtic went to in an attempt to out a mole leaking team news on social media.
The former Hoops boss admits he was furious after a long-term leaker was able to put out his team on a consistent basis, giving opponents a serious advantage.
And it led to the club employing a forensic IT company to check employees' phones as they tried to find out who was behind the information seeping out.
Speaking to BBC's 5 Live, he explained: "Even at Celtic, in my second spell, we would pick the team a day before. Then the team would be out on the wires at like 7pm that night. You're thinking 'it's coming from somewhere it's coming from somewhere in the building'. Sometimes, even the players can do you in if they're maybe out the team. It wouldn't have happened 10-15 years ago but it's such a common trend now. I am wary of naming a team a day before the game but it's what the players like.
"We played Jonny Hayes (September 2019), there's absolutely no way anybody could have known we were going to play Jonny Hayes on the left wing. I swear, at 6.30pm (Saturday night before game) it's all over Twitter. I was raging, you are just giving the opposition an advantage here. Because either someone is getting paid money for it or they are giving it to a betting company, or this guy is feeding them a few... I don't know. It was just so wrong on so many levels.
"It wasn't leaked to the media, it was leaked to somebody and this guy would put it on Twitter. Even under Brendan, nine times out of 10 was bang on with the team.
"Somebody in the dressing room or the building is doing this. We tried all sorts to stop it. I said we are bringing in forensic computer IT guys to check your phones and blah, blah.. And it stopped for a while. But then bang, it started again."
