The Reds cruised to victory over the champions, with Jurgen Klopp‘s side once again playing some breathtaking attacking football against dangerous opposition.
Coutinho was introduced as a second-half substitute, having arrived back later from international duty with Brazil last week, and he couldn’t hide his delight at Liverpool’s performance.
“It was an excellent game, an excellent performance by the team,” Coutinho told the official website.
“Everyone played very well, we did what the manager asked us to do. Everyone was very committed from the outset and we got a great result against a great team.
“It was a great game, attacking we were virtually perfect, so it was a great game that gives us confidence.
The 24-year-old also touched upon the Reds’ started to the season, saying he feels they are nicely poised to mount a title challenge in 2016/17.
“We’re on the right track, we’ve started the season well,” he added.
“Of course we’ve dropped points, but the competition is very long [and] we’ve beaten teams that, theoretically, will be up there fighting for the title, so that boosts our confidence, and the fans’ confidence. That’s very important.”
There has been much talk over whether Coutinho will win his place back for Friday’s trip to Chelsea, following such a superb performance by the front-three of Firmino, Mane and Sturridge.
Some feel Klopp should stick with exactly the same team that thumped Leicester, while others see Coutinho as too influential to leave out.
The most likely outcome is that Sturridge will make way for Coutinho, with Firmino deployed back down the middle, but you can never second-guess Klopp.
What it does show is the strength in depth Liverpool now have and the attacking options of real quality Klopp has at his disposal.
