The 2-0 defeat was inflicted courtesy of two second half goals, making it four games without a win during a miserable fortnight for Klopp’s side.
Liverpool had dominated the first half and created numerous good chances, but again couldn’t convert those and the second half saw the Foxes return the better team.
The first goal was scored by substitute Shinji Okazaki just after the hour, with Islam Slimani adding a second – but both were poor goals to concede and Klopp was clearly not happy with the defending.
“It’s actually easy to explain,” Klopp told Sky Sports in his post-match interview. “We played really good football in the first half, we should have decided the game early. We had big chances.
“[But] football is a 90-minute game. It’s a second ball after a corner, and a throw-in again – I’m sick of goals like this to be honest, it’s unbelievable.
“You need to stay concentrated to the end, they scored too easy. The first goal, we don’t push up together, I can’t say it 1 time, 1,000 times or whatever, it’s not nice to concede these goals and today it’s again because of this.”
Opposition throw in with everyone in position & concede 5 seconds later! Same as Saturday!!

Klopp has been reluctant to criticise his defenders this season, and has claimed numerous times that there were no other players to sign who were better than his current centre-backs, but even he know cannot hide his discontent in public.
Klopp made eight changes to the starting XI and the first half offered plenty of positives, but ultimately the same issues proved Liverpool’s undoing, with chances not taken at one end and chances being gifted too easily at the other.
Liverpool return to Leicester on Saturday in the Premier League, before trips to Moscow and Newcastle before the international break in October.
