In the Carabao Cup on Wednesday, Liverpool needed two second-half goals to beat Preston North End.
Against Jurgen Klopp's team, the Championship side put up a resolute display.
After 62 minutes, the deadlock was broken when Takumi Minamino smartly completed Neco Williams' cross.
With six minutes left, Divock Origi put the game out of reach with a spectacular backheel.
Klopp chose a very different Liverpool team than the one that beat Manchester United 5-0 on Sunday.
Preston seemed like they could cause an upset in the first half, but Frankie McAvoy's side failed to capitalize on their opportunities.
The Reds have advanced to the quarter-finals of the Carabao Cup.
