Kenny Miller doesn't believe any of Celtic's players are behind the leaked team news against Rangers on Saturday.
The Hoops suffered a horrible defeat to their rivals as their line-up was revealed hours before kick-off.
Neil Lennon hit out at the "disgusting" mole and says it's something the club will deal with going forward.
Rangers hero Miller insists it's incredibly hard to pinpoint the source as there is that many people around the club and the training ground.
But the striker seriously doubts it's one of the players who is the guilty party.
He told Sky Sports: “These things happen, if there actually is a leak I would seriously doubt if it was any of the players. There is that many people involved in football clubs and that many people in the training grounds.
“It might not have been done on purpose, it could have been leaked to someone who has done it through a third party.
“If he has an idea as to how it has got out it will be so disappointing because these things can be so vital.
“To be honest, when the team and formation comes out you know what is happening an hour before anyway.
“But if you’ve had that opportunity to prepare for it and it is something different – i.e. formation changes – it maybe gave Rangers a bit of a heads up and an opportunity to prepare for what they would be facing.”
