Steven Gerrard and Brendan Rodgers are set to lock horns on Sunday in a tie that has been dubbed as 'El Sackio' with both Aston Villa and Leicester City faring poorly so far this season.
The Foxes take on the Villans in a fixture that, generally speaking, has absolutely no bearing on proceedings in Scottish football in general. A bottom-of-the-table clash in England should provoke interest south of the border for two teams who quite frankly should not be fighting a relegation battle with the talent at their disposal.
But with the pair struggling, it has sparked tensions going into Sunday's fixture - and fans north of the English-Scottish border have sat up to take note. Of course, Rodgers and Gerrard both had brilliant spells in Glasgow, albeit at different teams with Celtic and Rangers. Both led their respective clubs to 'invincible' seasons. Rodgers won more trophies at Celtic including a double treble which of course set the Hoops on their way to the infamous 'quadruple treble'. Meanwhile, Gerrard took over Rangers in a worse state and although he didn't win as many honours, put the Blues back on the map again with their first title in over a decade, alongside strong European showings.
Yet the pair have a long history between themselves. Gerrard played under Rodgers whilst at Liverpool, with the Northern Irishman freezing the Reds legend out of the first team picture at Anfield as he aged with a more youthful team being preferred on Merseyside - much to Gerrard's surprise.
"I just wish I had met him when I was coming into my prime, maybe 25 or 26 years of age,' said Gerrard upon his exit from the Reds in 2015. "I'm sure we'd be standing here having won plenty more trophies."
Then, as Rodgers moved to Glasgow, he started to show his dominance. The boyhood Celtic fan turned the Hoops from Scotland's de-facto best side at the time into a genuinely dominant force; as evidenced by the 'double treble' that they won in his time as boss. But there was soon to be a new kid on the block that threatened to upheave and unravel all of Rodgers' good work. Gerrard was appointed as Rangers boss in 2018.
Two derbies followed before Rodgers departed for the King Power Stadium. Until now, he had absolutely breezed through Scottish football and the subsequent derby days that followed. None of Mark Warburton, Graeme Murty or Pedro Caixinha managed to topple the Carnlough-born leader in 12 attempts.
That did reach 13 thanks to an Olivier Ntcham strike at Celtic Park, although Gerrard's men put up a huge fight. The writing was on the wall that Rangers were finally beginning to return to their former self. And at the 14th attempt, Gerrard's men finally got their way. The apprentice had beaten the master, Rangers had ended their awful run of form and the picture began to shift in Glasgow.
Of course, Rodgers remains the more successful manager; not only the amount of titles in his time at Celtic Park, but his exploits at Leicester - until the start of this season - included two years of European football and an FA Cup, which were two extremely impressive achievements.
But for now, Gerrard can inflict more pain upon the man who he admittedly took a lot from in his earlier days of coaching. "It would have been very naive from my point of view not to try and learn as much as I can and what I could from Brendan," Gerrard said back in December of last year.
"I continued to do it even when we never worked together because obviously I came up against him in Scotland and I have seen how well he has done in the Premier League, which is certainly no surprise to me."
It promises to be a cracker which could see either manager squirmed out of their respective club.
