It was an intense evening for both clubs at the Anfield with different setup from the teams that played on the same grounds in the Premier League on Monday night.
The game went then the whole course of the 90 minutes with no goal but Arsenal were pretty wasteful in the early minutes of the game squandering chances that came begging.
Jurgen Klopp’s men continued their high pressing game at home with a midfield on youngsters and James Milner leading the team.
A class act from Arsenal goalkeeper Bernd Leno denied Liverpool three chances to go in front saving one from Diogo Jota, Virgil van Dijk and Grujic.
Rob Holding’s header from a cross after a short corner was taken by Arsenal tested Adrian in post in the second half but Nicolas Pepe struggled to create chances on the left-wing for the gunners.
Arsenal looked unlucky as Mohamed Elneny’s penalty kick was saved by Adrian but again Bernd Leno turned up and saved Origi’s penalty and brought them on level terms before saving another one from Harry Wilson as Joe Willock slotted the last spot kick past Adrian to win the game for the gunners.
Arsenal won the game 5-4 on penalty shootouts and will now face Manchester City at the Etihad for the quarter final of the Carabao Cup.
