When Rangers are in difficulty Celtic are obliged to make their rivals’ problems even more severe if they can.
But that ‘nice and beautiful house’ that Ange Postecoglou is in the act of building at Celtic Park is set to be the scene of a domestic dispute on Wednesday morning at the club’s AGM.
The look of disbelief on Ange’s face when last Sunday’s game at Dundee was interrupted by a fans’ tennis-ball protest was there for all to see.
The man who wants no distractions to get in the way of his re-building work will need to put up with another argumentative interlude concerning matters that have nothing to do with him.

Postecoglou will instinctively know that internal strife and a disconnect between the club and elements of the fan base can not assist him in his job of making the team successful.
Maybe when they get to the section marked Any Other Competent Business they should let Ange address the audience in his own distinctive manner.
