The goalkeeper spread himself well to deny Rodwell early on with a fine save and made a wonderful stop to deny Dzeko from close range. He could do nothing about City's goals and prevented a rout.
The Arsenal loanee is a promising talent but had a night to forget, almost gifting Dzeko another goal with a slip.
The centre-back put in a great last-ditch tackle to deny Navas an easy chance but the damage was already done.
Got forward well to provide support but that also left the defence badly exposed to City's counterattacks. Was beaten for pace down the flank by Navas and for strength by Dzeko but showed determination to set up Dyer.
The Polish defender got in a few good blocks but was not helped by the full-backs' positioning in the first half and struggled to track Dzeko.
The midfielder had a good chance early in the second half but could only shoot straight at Hart and was quiet apart from that.
Showed drive to get forward and drew a booking from Navas and made a nuisance of himself, blasting a deflected effort home to give the Foxes hope.
The Manchester United graduate was not at the races and struggled to cope with the quality of City's play. Never stopped running but did not have enough guile to alter proceedings.
The Frenchman struggled with the pace of City's play and was replaced by Pearson at half-time.
The former England striker failed to get into the game as he received little service from the midfield and was substituted for Schlupp.
The 32-year-old forward saw little of the ball and was withdrawn at the break.
The England No.1 had little to do in the first half but held on well to a drive from King on 50 minutes. Was unfortunate to lose his clean sheet to a deflected goal.
The 28-year-old started brightly and curled in a brilliant trademark free kick in from 30 yards after eight minutes. He would have had an assist but for a bad Dzeko miss.
The centre-back looked a little shaky at times, hoofing the ball clear when a calmer head would have eased the tension. Not the best way to force his way back into Pellegrini's plans.
The captain provided a measure of calm to a back line suffering from the nerves of Lescott and Boyata either side of him. Deflected Dyer's consolation effort in but put in a number of good blocks.
The influential right-back suffered a hamstring injury early on and could not continue. Replaced by Boyata.
The Spaniard ran the game from the middle, linking the play between midfield and attack with ease. Sumptuous passing earned him a standing ovation from the home crowd as he was subbed - a fine display.
The Spaniard picked up a deserved caution after gifting Dyer the ball early on but had the beating of Konchesky down the right wing.
The England midfielder hugged the left touchline from the off and struggled to link up with Kolarov but set up Dzeko for both his goals in an incisive display - he is fast becoming one of Pellegrini's most influential players.
Almost opened the scoring early on but was denied by Schmeichel. Stood strong in the centre and was positive in possession.
Showed tidy footwork to move the ball on in difficult positions, with Leicester pressing, to open up space for team-mates in the first half. A lack of discipline in the second period almost saw him collect a red card, though, and he became too casual.
An impudent early pass almost set up Rodwell and his dribbling skills won the free kick for Kolarov's opener. Missed a sitter from two yards but made amends with a predatory header and a second after the break. A fine all-round display.
Came on at half-time for Taylor-Fletcher but could not stem the flow of City's attacks.
Replaced Knockaert at the interval but did not get too involved as City strolled to victory.
Replaced Nugent with 25 minutes to go with the game already lost but his enthusiasm gave the fans belief.
