Here are the key takeaways from the game.
Jota the slotter
Liverpool fans have affectionately referred to the Portuguese as 'the slotter' and he lived up to that nickname with a perfect poacher's performance.
He found himself unmarked after Virgil Van Dijk's header was saved by Kasper Schmeichel and could not miss from less than six yards out.
Then in the 87th minute, he swivelled and smashed Joel Matip's nutmeg pass past the Dane after some great work from Luis Diaz.
It is extremely surprising that the Reds had a free-run on him considering his numbers, PL experience and the potential to scale-up those numbers.
Lively Luis Diaz
The Colombian was making his Premier League debut and he lived up to expectation.
Starting on the left, he found himself in central areas and on the right several times.
Many fans remarked that he looked like a 'Klopp' player already and that versatility combined with his work rate, pressing and composure suggest the Reds have unearthed another gem.
He was at home with the pace and physicality of the English game and looked like he has been a Liverpool player all season.
His debut could have been even better, but Schmeichel saved his stunning volleyed attempt in the 78th minute after Mohamed Salah had hit the crossbar.
The partnership he formed with Andy Robertson and Jota in the second half was particularly exciting, and drew comparisons with the Trent-Elliott-Salah connection on the right.
Salah shines without scoring
Mo Salah has often been criticised by rival fans for not performing well when he fails to score or assist in a game.
However, his return from the Africa Cup of Nations boosted the Anfield crowd and also the performance on the pitch.
He had several chances to make an impact on his return but it just wasn't his night as he was denied by Schmeichel and the post.
First, he danced through the Leicester defence but hit the Dane with his shot, then he ran through on goal and hit the keeper again.
His best chance came when he hit the crossbar from a stunning curling effort from just inside the box.
The Egyptian seemed determined to put the AFCON final defeat behind him and push on with his club to win the Golden Boot and potentially silverware.
Thiago terrorises the Foxes
Keeping Thiago Alcantara fit could define Liverpool's season. The Spaniard has formed a formidable partnership with Fabinho.
In the 17 matches they have played together, the Reds have won 16 and drawn one.
Thiago finished the game with four tackles, three interceptions and eight ball recoveries but it was his distribution and composure on the ball that stood out.
He was progressive and set the tempo high. His swagger was evident when he left James Maddison in his wake with a body swerve that delighted the Anfield faithful.
His confidence was embodied by the spectacular overhead kick he attempted from outside the box in the 42nd minute.
With Thiago and Fabinho's connection, there seems to be only one space in the Liverpool midfield for one of Harvey Elliott, Jordan Henderson, Naby Keita, Curtis Jones, Alex Oxlade-Chamberlain and James Milner to fight for.
Jurgen Klopp boasts arguably the best midfield options he has had in his tenure at Anfield.
This is probably true for the rest of the squad too as his attacking depth looks sensational and possibly the only position that the Reds lack depth in is right-back.
It promises to be an entertaining run-in.
