The two European giants boast a staggering 13 Champions League/European Cup crowns between them, six for the Reds and seven for the Rossoneri, who enter the match on the back of a 4-0 Serie A crushing of Venezia.
That emphatic victory saw Paulo Fonseca win his first match in charge at the fourth attempt, but in contrast, Arne Slot saw his 100% start come to an end on Saturday as Nottingham Forest stunned the Reds 1-0 at Anfield.
Here, Sports Mole takes an in-depth look at the head-to-head record and previous meetings between the two sides.

A match that is forever etched into the annals of the Champions League, Milan and Liverpool may have only met on four previous occasions in competitive action, but their inaugural meeting provided one of the most unforgettable nights the tournament has ever seen.
Nothing more can be said about the 2005 Miracle of Istanbul that has not already been said, as Rafael Benitez's Liverpool pulled off the improbable by fighting back from three goals down to take that year's Champions League final to the unlikeliest of penalty shootouts.
Up steps Jerzy Dudek, who after producing a magnificent double save from Andriy Shevchenko in extra time also denied the Ukrainian and Andrea Pirlo from the penalty shootout; cue the scenes of Steven Gerrard hoisting the famous trophy aloft.
A miffed Milan avenged that agonising defeat two years later, though, when Filippo Inzaghi was at the double in the 2006-07 Champions League final to secure Milan's seventh and most recent triumph in the competition; Dirk Kuyt's effort was a mere consolation in Athens.
After locking horns twice in finals in the space of three years, Liverpool and Milan had to wait another 14 years to cross paths again in the Champions League, and in keeping with Reds-Rossoneri tradition, their September 2021 showdown was a thriller.
In front of the Kop, Liverpool emerged victorious by a 3-2 scoreline as Jordan Henderson's 69th-minute drive settled a gripping group-stage showdown, where Brahim Diaz, Ante Rebic, Mohamed Salah and Fikayo Tomori - in the wrong goal - also registered.
Liverpool made it two for two at San Siro a couple of months later, thanks to another effort from the timeless Salah and favourite son Divock Origi, who is now out in the cold at AC Milan after being banished from the first team.
That 2-1 triumph was actually Liverpool's second of three straight wins at Milan's home - they have also defeated Inter Milan away from home twice in 2008 and 2022 - meaning that the Reds are the only team to visit San Siro more than once in the Champions League and hold a 100% record.
