Liverpool manager Jurgen Klopp has threatened to quit the Carabao Cup if the EFL do not accommodate their packed fixture schedule.
A 5-4 penalty shootout win over Arsenal, after a crazy, thrilling 5-5 draw at Anfield in which Divock Origi scored his second of the game to equalise in the fourth minute of added time, put the Reds into the quarter-finals.
Match dates for the last-eight round are scheduled for the week commencing December 16 – when Liverpool will be in Qatar at the FIFA Club World Cup.
