Despite Coutinho warning his side against complacency, the Reds still collapsed against the Foxes.
Liverpool legend Jamie Carragher was upset with how Jurgen Klopp's Reds fell at the King Power stadium on Monday night.
The Premier League champions Leicester City smashed Liverpool 3-1, with Jamie Vardy scoring a brace and Danny Drinkwater hitting the target with a sublime strike as the Foxes sealed their first league win in 2017 following the sacking of Claudio Ranieri. Phillipe Coutinho helped score a consolation goal Liverpool.
However, following Liverpool's defeat, Carragher blasted Klopp's tactics and their all-round display.
"Liverpool were shocking tonight, I was at the games at Hull and Burnley and they were the exact same games," Carragher told Sky Sports. "They're on course to concede 50 goals again this season and Klopp hasn't rectified that.
"There's no way you are going to win anything conceding that amount of goals, it's just impossible to do that.
"My other problem is Liverpool always play the same way, and I said it again before the match. What's wrong with Liverpool going to a side like Leicester and saying, 'Let Wes Morgan and Robert Huth have the ball, we know Vardy wants to spin in behind. We can hit you on the break with Sadio Mane.'
"It's always the same thing that happens for Liverpool -- it was [Burnley's Andre] Gray and [Hull's Oumar] Niasse before and Vardy tonight -- I just don't know why it hasn't changed.
"There's no difference in tactics, there's not a different plan for certain games. I think Klopp has far too much faith in certain players. He has to make changes in the summer."
