Liverpool boss Jurgen Klopp defended his decision to substitute Philippe Coutinho but admitted he has been left feeling 'sick' by the Reds after their Carabao Cup exit at Leicester.
The Foxes dumped Liverpool out in the third round after Shinji Okazaki and Islam Slimani scored to clinch a 2-0 win at the King Power Stadium on Tuesday.
It came after the visitors dominated the first half as Coutinho, Alex Oxlade-Chamberlain and Dominic Solanke missed fine chances.
Coutinho was withdrawn at the break as he builds fitness after an interrupted opening to the season, where Liverpool rejected several bids from Barcelona.
