Liverpool sealed their place in the League Cup semi-finals with a 2-0 victory over Championship side Leeds United on Tuesday night.
With Steven Gerrard watching on from the stands, Ben Woodburn was named on the substitutes’ bench for the second game running.
Leeds made some dangerous strides into the final third, with the likes of Alberto Moreno needing to be on their toes in defensive situations.
Liverpool were held to a 0-0 draw at half-time, but Klopp remained patient, waiting until the 66th minute to send Woodburn on for Kevin Stewart.
Before Woodburn could make an impact, Alexander-Arnold sent Divock Origi through for Liverpool’s opener, bending a sensational cross behind the defence for the Belgian to nudge home.
This provided the lift the home side needed, and six minutes later, Woodburn netted the Reds’ second of the night, becoming the club’s youngest ever goalscorer.
This was an emphatic moment for all of Merseyside, with Woodburn swarmed by his team-mates and, at full-time, embraced by a proud German.
Klopp’s side are now unbeaten in 15 games, with Woodburn’s strike yet another positive in a remarkable season so far.
