Just 32 miles separate Liverpool and Manchester United and the rivalry has been fierce for decades between, historically, England's two most successful teams.
The two clubs have won 39 league titles between them, with United claiming 20 championship successes to Liverpool's 19.
It's the Merseysiders that have had the better of the recent meetings, with victories in four of the last five clashes between the teams.
The latest encounter between these two giants is at 16:30 on Sunday, 17th December, with Liverpool going into the weekend sitting top of the Premier League table.
The return fixture, at Old Trafford, is due to take place on the weekend of 6th April, 2024.
The first Premier League game between the rivals in the 2023-24 season will take place at Liverpool's home, Anfield.
Jurgen Klopp's men have won this clash on home soil in the last two meetings, with a 7-0 success in 2022-23 and a 4-0 victory in 2021-22.
The Sunday, 17th December fixture will be shown on Sky Sports Main Event, as well as on Sky Sports Premier League.
If the pair are drawn against each other in the FA Cup, that match would be shown live on either the BBC or ITV.
This is a long-time rivalry and the 17th December fixture will be the 212th meeting between the two sides.
Manchester United have the edge in the head-to-head stats, winning 82 of the matches compared to 71 for Liverpool, and there have been 58 draws.

Peter Beardsley is the other player to have been at both clubs, although he only made one senior appearance for United in a one-season stay in 1982-83. He is better remembered though for his time at Anfield, where he won two league titles and an FA Cup between 1987 and 1991.
