Take a look at the Scottish Premiership table and it's like the last 10 years have never happened.
For the first time in the 2018/19, Celtic now occupy the top spot on points, with Rangers just two behind them in second.
When Steven Gerrard took charge, few would have predicted that his new club would be able to overhaul their bitter rivals as quickly as this season.
That said, as it stands, just the Old Firm back in September is separating them.
The Hoops won that fixture 1-0 thanks to a goal from Olivier Ntcham, though that scoreline flattered Rangers and Rodgers' men ought to have won by a greater margin.
Nevertheless, an Old Firm victory always prompts wild celebrations at the final whistle and the entire team embarked on a lap of honour around Celtic Park.
Understandably, they wanted to applaud the home crowd - but, of course, it didn't go down well with the 800 or so fans in the Rangers end, who felt the Celtic players deliberately stopped in front of them.
It sparked unsavoury scenes, with the Glasgow Evening Times suggesting disabled fans were knocked over amid the agitation.
Celtic players have been criticised
The newspaper also claim that the lap of honour could now be banned after a police memo blamed Celtic players for the ensuing trouble.
A superintendent said there was a "clear link between the between the actions of the Celtic players (which immediately inflamed an already delicate situation) and the subsequent response of the Rangers fans".
At the club AGM this week, Rangers chief Stewart Robertson made the following complaints, as quoted via The Scottish Sun:
“Players have to be very careful about their actions, during games and after games, because every action can have a reaction as we saw that day.
“So we need to…we just can’t have a repeat of that."
Brendan Rodgers responds
In turn, Brendan Rodgers has defended his players and insisted they acknowledge their supporters at every game - so the Old Firm should be no different.
"I think it's a little bit unfair on the Celtic support," he said.
"I make sure that after each game, whether we win, lose or draw, we always acknowledge the supporters. Because they travel from far and wide, up and down Scotland, across from Ireland, from all over the world. And it's something that the players and myself have always done, is recognise that.
"So whether we have won, whether we have lost, whether we have drawn, whether it's against Rangers, whether it's against Inverness or Ross County or Livingston or Hamilton, we always do it. So it's not so much a lap of honour in that last game.
"But I also think it's unfair to put the responsibility of away supporters on to Celtic players."
Tensions are always going to be heightened on Derby Day.
While it might seem like an over-reaction, it's understandable that security are going to do their best to contain what is a very delicate situation.
