Liverpool and Manchester United renew rivalries at Anfield on Sunday in the latest clash of English football's superpowers.
Just as United's 26 years without a league title from 1967 did not devalue the confrontations, so they have endured during Liverpool's present 23 season barren spell.
Here, Press Association Sport looks back at some of the more notable Premier League encounters.
