Takumi Minamino scored twice as Liverpool beat fellow Premier League side Norwich City at Carrow Road to reach the Carabao Cup fourth round.
The visitors led after four minutes as Minamino produced a sharp turn and finish from Divock Origi's knockdown.
Caoimhin Kelleher denied Norwich an equaliser before half-time, saving Christos Tzolis' penalty with his foot.
Origi headed in Konstantinos Tsimikas' cross five minutes after the break and Minamino slotted in a late third.
Both managers made nine changes from the weekend's Premier League matches, with Liverpool boss Jurgen Klopp handing debuts to teenagers Kaide Gordon and Conor Bradley from the start - plus Tyler Morton as a substitute.
