Yesterday was probably a turning point in a title race that shouldn’t even be extant in the first place.
The failure of Celtic to sign three out of four signing targets in the summer created a malaise in the squad.
The 11th hour departure of Moussa Dembélé only exacerbated matters.
Brendan was clearly unhappy with those tasked to execute the paperwork end of the transfers.
The Boyata business in Athens only added to the element of Greek tragedy that was surrounding Celtic at the time.
In a ridiculously short period, the champions had gone from open-top bus to open disharmony.
The final fixture of the calendar year will tell if Celtic are finally back in the groove.
The chap in the home dugout at Ibrox will experience severe pressure if his old gaffer prevails.
Then Mr Gerrard will have to see if his squad emerges from the January window largely intact.
Regular readers here will not be surprised that Alfredo José Morelos Aviléz is expecting offers for his services in the January window.
As previously reported here, folk in agent land have known for several months that some Sevco players are quietly up for sale in January if the price is right.
The Colombian striker is one of four Ibrox players that could help to balance the books if they were sold into the inflated English market.
When Mr Gerrard complained about this proposed course of action, he was told that with his contacts he could surely source promising young players from top English clubs on loan to replace them.
It was during this period that he stated that he would “fall out with people” over his star striker.
At that time an excellently placed source told me that James Tavernier, “one of the Croatians and one of the goalkeepers” completed the quartet.
Of course, players must want to move, but the very fact that these moves have been discussed shows the difference in perception between Mr Gerrard and the chaps in the Blue Room.
Across the city, Celtic cannot surely fail in three consecutive transfer windows.
This time last year the main acquisitions were Marvin Compper and Charly Musonda.
Just like yesterday at Pittodrie, if Celtic go about their business competently the opposition and the officials cannot halt eight in a row.
I hope that you’re having a great holiday.
