Manchester United manager Erik ten Hag says his players will be "angry" when they face Liverpool and called on them to "bring big games over the line".
United conceded twice in stoppage time for a dramatic 4-3 loss to Chelsea on Thursday, five days after letting in a 99th-minute equaliser at Brentford.
Those results have left them sixth in the table before hosting Jurgen Klopp's title-chasers on Sunday (15:30 BST).
"We have to step up and make better decisions," said Ten Hag.
The five points United have dropped late in their past two league games have left their hopes of qualifying for next season's revamped Champions League hanging by a thread.
