Liverpool defender Andy Robertson has identified one thing that his side need to put an end to as soon as possible.
The Reds took the lead midway through the second-half after a piece of magic from Roberto Firmino found Mohamed Salah, who continued his fine form in front of goal.
It was a dominant performance from the champions up until that point and there were signs of last season's side in the opening 75 minutes.
However, a seven-minute blitz from Leicester saw Liverpool's lead quickly overturned as their poor run of form continued.
Robertson believes the squad need to improve their defending with some huge games on the horizon.
"Yeah, it’s a huge blow, you can say that," he told BT Sport. "I thought for large parts of the game, we were really good, dominant when you come here against a really good Leicester team.
"Not many teams do that and then the thing we’re struggling with is that’s not us out there. One setback and we’ve been so good at bouncing back, we stay in the game, but with that setback, we just opened up and played right into Leicester’s hands with Barnes and Vardy, the pace and the counter-attack.
"We just opened completely up and when that happens against a really good Leicester team, you’re going to get punished.
"We were great for 75 minutes, but that’s not enough to win football matches and we’ve been on the wrong end of it today.
“Look, confidence, I think for large parts of the game we played with a lot of confidence. We kept the ball really well, we started really well, created a couple of chances, a few good corners in the first 10 minutes, started the way we wanted, then I don’t know what happened in the last 15.
"That can’t happen in a big game like this, it simply can’t and it did unfortunately for us, so we really need to look at that.
"We have some really big games coming up, every game is massive for us now and when you open up like that, most teams will punish you and we really need to put an end to it.”
The Reds travel to Budapest on Tuesday evening for the first-leg of their Champions League Round of 16 tie against RB Leipzig.
After that, Klopp's side welcome Everton to Anfield for this season's second Merseyside derby, with the Toffees set to challenge Liverpool for a top four position this term.
