After watching his side fall to a 2-0 loss to their bitter rivals Celtic last weekend, Rangers boss Pedro Caixinhia held crisis talks with his players where it was reported that he scolded his Scottish players for not making him feel welcome since his arrival, amongst other things.
The mere fact that this was reported at all, after what was supposed to be a private meeting with his first-team players, is a massive problem as someone clearly briefed the media as to what had been discussed.
When Kenny Miller was demoted to the Rangers U20 squad later in the week, and was not named in the squad for Friday night's trip to Hamilton, it seemed obvious that the source of this leak had been found, but nothing has been confirmed as of yet so for the moment that is still speculation.
Speaking before that meeting between Rangers and Hamilton on BT Sport, Chris Sutton addressed these developments and gave his backing to Pedro Caixinha by claiming that he should immediately sack the 'rat' that is trying to make things more difficult for him.
The dogs may be barking at the caravan but there's a rat inside. Something has to give now. If he knows who the rat is he should sack him. There is absolutely no doubt about that it just has to happen.
When you have a private meeting at a football club it should stay in the dressing room. The person who leaks the details of that meeting, what was his desired outcome? The desired must have wanted to cause problems for the manager.
That person must not want Pedro Caixinha at the football club so find out who he is and out him. Get the rat out. What chance does he have as manager if he has a traitor in the dressing room?
While he's absolutely correct, it's slightly unusual that Sutton is not enjoying this situation a wee bit more.
He has not exactly been the biggest Pedro Caixinha fan since the Portuguese landed in Glasgow, but in this case Sutton is bang on the money that there is no place for someone who is acting in such a treacherous manner in the dressing room.
That said, Caixinha is remaining tight-lipped, and played down Miller's absence from the squad while speaking to BT Sport:
It is not a question of having a problem with anyone, it's a question of decisions I took in picking my squad and he's not with us.
When asked directly whether or not Kenny Miller was left out because of the leaked meeting details, he refused to be drawn on it, so this issue may rumble on at Rangers for a while yet.
