Liverpool return to Old Trafford on Sunday with revenge on their minds, knowing that anything less than a win will not suffice as Manchester United seek to derail their fiercest rivals' Premier League title challenge.
Last month, these two clubs played one of the season's most exciting FA Cup games. United won in the most dramatic of circumstances, ending Jurgen Klopp's quadruple ambitions and keeping their season alive.
A defiant Erik ten Hag has insisted that he has "no doubts" about remaining Manchester United's manager next season ahead of Sunday's game.
"I'm just focused on my job, this process, and this project. I really enjoy being here. For me, it is a challenge.
Erik ten Hag warned Liverpool that United would be "angry" following their defeat to Chelsea on Thursday, saying, "We will keep fighting."
Jurgen Klopp has won just twice and drawn four of Liverpool's ten visits to Old Trafford as manager, with one of his four defeats coming in dramatic fashion in the FA Cup last month as their quadruple hopes were dashed.
Klopp understands that if his team is to maintain their lead in the Premier League title race, they must correct the mistakes they made in that 4-3 defeat. He says, "We were really good that day, but we didn't finish the situations off."
