Jurgen Klopp warned his stars they "should have played better" despite Liverpool advancing to the FA Cup semi-finals with victory over Nottingham Forest.
Diogo Jota scored the only goal of an end-to-end last-eight tie on Sunday evening to set up a Wembley clash with Manchester City in mid-April. The Portuguese forward's goal came as Forest pushed to take the lead and the Championship side also had chances to hit back after falling behind in the 78th minute.
Philip Zinckernagel squandered a brilliant chance from close range before Alisson avoided conceding a penalty after his outstretched hand made contact with Ryan Yates' foot. Klopp made plenty of changes for the trip to the City Ground but admits he expected Liverpool's performance to be much better.
