Wilfried Nancy and Danny Rohl have both joined a list that only features four Celtic and Rangers managers.
Nancy will take charge of the Hoops in a Glasgow derby for the first time while Rohl has had previous experience.
Celtic beat Rangers 3-1 in the Premier Sports Cup semi-final and are in desperate to repeat that, with the Frenchman under huge pressure.
Regardless of what happens, the two have made history.
The starting XI is in. Any changes you would’ve made?
Wilfried Nancy and Danny Rohl join little-known list
As per the BBC Sport head-to-head guide, Nancy and Rohl will be making history.
For only the fifth time in history, the managers of both teams will be taking charge of their first Scottish Premiership Glasgow derby at the same time.
Billy McNeil, John Greig), August 1991 (Liam Brady, Walter Smith), September 1998 (Jozef Venglos, Dick Advocaat) and September 2016 (Brendan Rodgers, Mark Warburton) are the only other occasions that this has happened.
It will only be considered a memorable one for the current Hoops manager if he can pick up the all-important three points.
What do you think? Is the league title still salvageable? Let us know in the comments.
Wilfried Nancy on facing Rangers for the first time
Facing the big rivals is a daunting prospect for anyone, but Nancy is confident that he can rise to the challenge.
The 48-year-old went on a passionate rant about his abject start in Glasgow, but is determined to bring the feel-good factor back.
He said: “We want to win every game. I know that this game is important because of the rivalry but it doesn’t change the desire to win, the desire to compete, the desire to do well.”
