Claudio Bravo was Manchester City’s penalty hero as they kept their hopes of a dream quadruple alive to beat Leicester and reach the Carabao Cup semi finals.
The goalkeeper saved Riyad Mahrez’s spot-kick as Pep Guardiola’s side won 4-3 on penalties following a 1-1 draw after extra time.
Jamie Vardy also missed in the shoot-out after scoring a controversial added-time penalty to take it beyond 90 minutes, after Bernado Silva’s first-half goal looked to have given the visitors the win.
They can still take a clean sweep of trophies this term, with Guardiola’s side 11 points clear at the top of the Premier League.
Arsenal are second-favourites after Danny Welbeck bundling in the only goal of the game from close range.
Leicester boss Claude Puel conceded before Tuesday night’s game even if City made wholesale changes their team would still be one of the best in Europe.
Yet Puel’s decision to leave Mahrez, Vardy and Demarai Gray on the bench until the second half ultimately backfired.
Only Ilkay Gundogan and Eliaquim Mangala started for City following Saturday’s 4-1 win over Tottenham.
The Foxes trio put the visitors on the back foot but could not end Guardiola’s domestic dominance.
City, who have won the trophy twice in the last four years, bossed a low-tempo start which began to ignite when Silva forced Ben Hamer into a smart 13th-minute stop.
Leicester then almost gifted the visitors the lead in the next attack when Christian Fuchs and Hamer collided and Gundogan had his goalbound shot blocked.
Gundogan, who scored his first goal of the season against Tottenham, was seeking more and Hamer tipped his chip over.
The Foxes started slowly and Kelechi Iheanacho, who moved from the Etihad to Leicester for £25million in the summer, struggled to make an impact before he helped his old club to a 26th-minute opener.
Iheanacho allowed Yaya Toure to take the ball, Gundogan strode forward to find Silva and the winger prodded the ball under the onrushing Hamer.
With the lead City were comfortable but Bravo had to react well to Iheanacho’s low shot after 33 minutes. It gave Leicester belief with Bravo unsettled and Iheanacho shot over following the goalkeeper’s hurried clearance.
The hosts continued to rattle City thanks to the arrival of Mahrez and Vardy 11 minutes after the break but failed to create clear openings and the most Guardiola had to be worried about was when a pitch invader was dragged past him.
The arrival of Gray signalled Leicester’s intent and Mahrez almost levelled when his angled effort was gathered by Bravo with 10 minutes left.
They did equalise in the seventh of eight minutes of stoppage time when Kyle Walker tangled with Gray in the area and Vardy buried the penalty. It was a soft decision and Walker had penalty claims of his own turned down in extra time, while Bravo saved well from Mahrez before the shoot-out.
Fuchs, Harry Maguire and Vicente Iborra scored for Leicester while Gundogan, Toure, Lukas Nmecha and Gabriel Jesus netted for City. But, at 4-3, Vardy’s penalty hit the post and Bravo dived to his left to deny Mahrez.
Manchester City boss Pep Guardiola was “so happy” to see his young side progress but ruled out a potential quadruple.
“Forget about it. That is not going to happen,” said the Spaniard.
When asked about the penalty, Guardiola preferred to focus on the positives.
“We will see if it’s a penalty or not but what I liked the most is how we reacted and overcame that situation,” he added. “That’s a good sign for our future.”
Claude Puel was disappointed to see Leicester bow out of the competition but pleased with his side’s response following Saturday’s 3-0 defeat at home to struggling Crystal Palace.
“It was a very good game between two good teams. It’s a disappointment of course but there are no regrets as we gave our best,” said the Foxes boss.
“We had a lot of chances to score tonight and I like this positive outlook and we got a response after the last game.”
