BBC Sport Holders Manchester City edged through for vanguard sports ,
Pep Guardiola’s side took the lead in the first half through Kevin de Bruyne’s first goal of the season – a sweet low drive into the bottom corner.
League One side Burton shocked the Championship’s Middlesbrough to also advance to the last four, while Arsenal face London rivals Tottenham and Chelsea host Bournemouth in Wednesday’s remaining quarter-finals.
Leicester were poor in the opening 45 minutes but regrouped at half-time and levelled the contest through Marc Albrighton’s well-struck effort before crumbling in the shootout.
Stand-in Muric the hero for City
Guardiola demonstrated how seriously he is taking the competition by selecting a team that blended experience and youth with first-team regulars such as Sergio Aguero, De Bruyne and Kyle Walker starting alongside youngsters Phil Foden, Eric Garcia and Brahim Diaz.
Argentina striker Aguero returned from injury and had an effort palmed out by Danny Ward while the Foxes goalkeeper also kept out Foden’s snapshot from the edge of the box.
‘It was a good game’ – Guardiola
Manchester City manager Pep Guardiola on Sky Sports: “A tough game – it is always difficult at Leicester. We played with a guy who is 17 years old and some injured players, it was a good game.
“Raheem Sterling took that decision [to chip his penalty], unfortunately he missed it but that is OK.”
Manchester City goalscorer Kevin de Bruyne on Sky Sports: “It’s a relief, it was difficult for us. It was a lot of players who hadn’t played a lot. We did a good game, it was an open game and in the end the keeper helped us. He’s got veins of ice! He did what he had to do in the shootout.
Analysis – Puel will be disappointed
City did not put Leicester to bed and the home side made it hard for them in the second half.
Claude Puel changed the game with his substitutions, it was not going for them and they got back into it. Albrighton scored a fabulous goal but Puel will be disappointed because the penalties from his side were very, very poor.
