The Blues will next face Manchester United in the semi-final as the draws were made moments ago.
Chelsea performed admirably away from home, and here are our Chelsea player ratings from what transpired.
Chelsea Player Ratings vs Leicester City
Willy Caballero: 6.5/10
The veteran custodian made a few commendable stops, including saves to deny Jamie Vardy and Youri Tielemans. Was troubled later on in the game, but came out unscathed.
Reece James: 4/10
James struggled to create any openings while going forward, and looked shaky at the back as well. He was rightfully substituted at half-time.
Antonio Rudiger: 7/10
Arguably Chelsea’s best defender against the Foxes, Rudiger was resilient and monitored Vardy from close quarters. He won three aerial duels, made one tackle, and played an instrumental role in the build-up to the only goal of the game.
Kurt Zouma: 6/10
Zouma had several nervy moments while playing out from the back, but settled as the game progressed. Needs to improve his passing from the back as he invites trouble at times.
Emerson Palmieri: 5/10
The left-back played within himself, and did not offer too much offensively. Defensively, however, he did a decent job.
Mason Mount: 4/10
Mount failed to stamp his authority on the game in the first half as Leicester had the better of the early exchanges. He was taken off for his lack of impact on the game.
N’Golo Kanté: 6/10
Tenacious as always, Kanté made three tackles and shielded his side’s defensive line with resolve. Although he found it difficult to push forward before the interval, the substitutions by Frank Lampard helped the Frenchman as he performed better with the likes of Mateo Kovacic and Ross Barkley.
Billy Gilmour: 4/10
Another player who was substituted at half-time, Gilmour lacked precision with his passing and looked nervous at times. The teenager has been impressive for the Blues, but it wasn’t his day today.
The winger kept popping up in the right areas and posed a threat to Ben Chilwell. He was given too much time on the ball and nicely picked out Barkley with his cross for the opener.
Tammy Abraham: 6/10
Abraham came up against the disciplined central defensive pairing of Jonny Evans and Caglar Soyuncu, and didn’t have much joy. Although his link-up play was up to the mark, he never really got enough chances to trouble the scorers.
Christian Pulisic: 7/10
His fierce strike was saved well by Kasper Schmeichel, and Leicester found it hard to stop his driving runs. His influence in the attack is growing with each passing game, and he will be a key player in the final stretch of games this season.
Mateo Kovacic: 7/10
From the moment he came on, the Blues looked sharper in midfield as he steadied the ship and orchestrated the play pretty well.
Cesar Azpilicueta: 7/10
Provided an offensive outlet from the right in place of the passive James, and he also tracked back timely to defend.
Ross Barkley: 7/10
The England international took his chance well, and could have got another goal to his name had he not squandered an excellent opportunity later on.
Ruben Loftus-Cheek: 5/10
The young midfielder made good use of his strong physicality and gained some valuable minutes in his quest to be more match fit.
Despite his brief cameo for the London based outfit, he made a good impact with his pace and clever movements with the ball.
