It's been a powder-keg issue since it was first announced, and tensions continue to rise over the Sydney Super Cup.
The idea of taking the Old Firm on the road was immediately rejected by both Rangers and Celtic fans in vocal protests from the stands.
Since the tournament was rubber stamped earlier this month, fans have only grown more fuming that the fixture is set to go ahead in Oz.
The latest episode came at Dens Park with Rangers supporters launched tennis balls and toilet paper onto the pitch on three occasions forcing the game to be stopped.
Murmuring under the surface has been the views of fan group Club 1872, who have taken aim at the board off the back of the friendly clash.
Sparks flew on Tuesday as Club 1872 fired a scratching statement in the director of the Ibrox board before the club responded with a hard-hitting blast of their own.
We've heard from all parties at this point, but what will the mood be like in the dressing room? What are the legends of the past saying about the rivalries road trip?
Record Sport takes a look at the Rangers heroes who have had their say.
Mark Hateley
“You have got a 150-year-old football club and the biggest partner ever, and you can call them a sponsor or a partner, is the supporters. They are why the club is 150 years old. Generation after generation have invested into Rangers Football Club.
“I have been involved at every level of the game from player to coach to manager and you have to engage with everybody within the football club. It’s not rocket science. You have to understand people.
“It’s a touchy subject, but if everything had been done slightly differently. It is what it is. For me, looking in from the outside, it has not been done properly.
“For me, in any walk of life or any business, you have got to know the people you are working with and the people who are supporting you in different parts of the organisation. Football is no different.”
Barry Ferguson
"I understand both sides. I understand where the fans are coming from and I also understand that the club want it. Financially it's a lot of money.
"Sing, demonstrate, hold banners up, but when the tennis balls and toilet rolls start coming on it is annoying. It's not ideal, but Rangers overcame it."
Kris Boyd
"I think the fans are the main people at a football club; they want to be heard. There's a way to do it. We don't want to see the games stop start.
"I think from the game today (against Dundee), as a player, you don't want it. You want to get on with it so from a players point of view, on the pitch it needs to stop.
"We seen the exact same with Celtic up here at the start of the season.
"Listen, if that's the way they want to voice their opinions. I don't agree with it and we are going to have to find a solution."
Graeme Souness
“In commercial terms it all makes sense. Money makes the world go round, especially in football, and that’s never been more the case than right now.
“You have to get out there and chase the bucks, making yourself (as rich) as you can. Neither Rangers nor Celtic don’t get much money by comparison to very small teams in the English Premier League.
“The purists say don’t go. Why? Because it’s just not right. But you want to see better players playing for your club and it’s about finding a market where they can generate interest in Rangers that can be monetised.
"That can end up with better players on the pitch. End of story.”
Craig Moore
"There'll be huge support for this match because unfortunately maybe the couple of years of Covid they haven't had the chance to come over and watch their team in Glasgow, so to have that opportunity in Australia I think it's fantastic for the supporters in that country.
"I can understand a little bit some of the supporters getting their knickers in a twist.
"Ange in terms of the Australian manager, part of Celtic, coming back to Australia. I think the Rangers supporters will feel as if they're like a bolt-on or in the shadows of this particular deal."
Brian Laudrup
"I think you have to understand both sides of this dilemma. As fans, they are upset about decisions made by the Rangers board and the only way they can show that is at games.
"It's not nice what is going on off the pitch just now at Rangers because you want to be united at this point of the season when there is so much at stake. There are clearly some problems there.
"A sentence with 'Old Firm' and 'friendly' in it does not ring too well in my ears."
Andy Halliday
“I personally think it’s an absolute embarrassment. Scotland as a whole stands out because how passionate the fans are. The Old Firm, Hearts v Hibs, Dundee derby, Aberdeen, the full thing.
“This is a tourist show. People are talking about financial benefits. Rangers’ biggest contributor to their finances is their fans and they aren’t having it.
“There’s far too much over-commercialisation with Rangers and the Old Firm."
Chris Burke
"About the trip to Australia, I don't see the problem with it to be honest. I think as much as they are saying it's an Ange homecoming, I think Rangers should use it in a different way.
"They are there to disrupt the homecoming, and they are there for financial reasons.
"It's something like £3million they earn from this. Although they (the protestors) are saying they should never play their rivals in a friendly, but I'm sorry it's 2022 now and the game has evolved.
"If you are not comfortable now, just wait for where we are in 10 years. With Celtic and Rangers playing in a different country, they could be playing down in England soon for a friendly."
