Leicester 2-3 Sheffield United witnessed fierce boos and chants as more and more home fans opted to leave with 30 minutes still remaining.
It required only two minutes for Sheffield United to take the lead, former Foxes forward Tom Cannon sliding on his knees in celebration for his third goal in a Blades jersey.
Leicester making an absolute mess of playing out from the back, failed to deal with a cross, with Cannon sending it underneath Asmir Begovic.
It became 2-0 on 4 minutes, a brilliant strike from Callum O’Hare taking a deflection off Jairo Riedewald on its way in.
The hosts failed to clear a corner properly, with Wout Faes’ header being volleyed back into the net from 18 yards by O’Hare.
Matty Fryatt (Ex-Leicester City striker on Radio Leicester): “It’s the worst possible start. The only thing I can say is from this position there’s no pressure because you now expect Sheffield United to go and win the game. What a start for them, they’re a team in form and full of confidence.
Andrew Aloia (BBC Sport England at King Power Stadium): “I’ve come by stunned silence in stadiums plenty of times, but the reaction to the second goal from Sheffield United can only be described as rumbling groans of disbelief. And there are still Leicester City fans finding their seats. They have missed nothing but carnage at this point.”
It became 3-0 just after the half-hour mark, Leicester cleared a corner, only for it to fall to Sydie Peck, who unleashed a volley past Asmir Begovic.
Carl Asaba (Ex-Sheffield United striker on BBC Radio Sheffield): “What a strike, what control! He got his knee over the ball and just let fly. That’s a difficult ball to hit, what a strike.”
Andrew Aloia (BBC Sport England at King Power Stadium): “A bad day gets worse for Leicester City. But oh my days, isn’t Sheffield United’s resurgence looking a little bit special right now.”
“That goal from Sydie Peck is the pick of the three first-half goals, and has Foxes fans getting out of their seats early for a half-time comfort break. It keeps going this way, and the empty pockets of seats might grow before this game is done.”
Adam Oxley (BBC Radio Sheffield): “‘Are you Wednesday in disguise?’ the Blades fans sing. Leicester City are shaking here, Sheffield United will look to go once more.”
Sheffield United fans could be heard chanting “you’re getting sacked in the morning” at Leicester boss Marti Cifuentes, with Leicester supporters briefly joining in. Security stewards also surrounded the directors’ box at half time.
“You’re not fit to wear the shirt,” rang around King Power Stadium.

Stephy Mavididi got one back for Leicester shortly into the second half, Abdul Fatawu with a cross to the far post, meeting Mavididi to grab his second goal of the season.
Leicester then got themselves a second goal with less than 10 minutes remaining, this one lashed in by Jordan James from 25-yards after Sheffield United lost the ball inside their own half.
Sheffield United held on to make it three wins in a row, climbing up to 19th in the Championship with 19 points from 18 games played, Leicester are 15th with 24 points from the same amount of games played.
Here’s how fans reacted after Leicester 2-3 Sheffield United and loud boos and chants as the home fans leave on 30th minutes…
@Elm_665: I left on 60 minutes on Tuesday, the earliest I’ve ever left a game… today I left at halftime. (Could have left after 5 minutes) If that’s not a damning indictment of this football club, I don’t know what is. #LCFC
@Son__gains: in response to those calling for Marti to be sacked. Who next to then be sacked until this squad is FULLY changed. This squad isn’t Marti’s, wasn’t Ruuds. wasn’t Coopers. wasn’t Enzos. Its a failed aged premier league team STILL on Champions League wages. Its Rudkins team.
@Ultra_Fox: 2-3 ft. The result was never truly in doubt after first-half shambles, but Mavididi and James goals made the game look more of a contest. Maybe #LCFC could bring Martin O’Neill back for a few weeks, like Celtic did. Cifuentes is finished, as is the man above him. #RudkinOut
@Birdiex94x: JJ and the subs can leave with head held high. The less said about most of the others the better.
@seanfromenderby: Unlucky not to win that, real fighting spirit from the lads shown. Work hard on the training pitch n go again #lcfc
@richhollis14: Yes the second half performance was better and we showed a bit of fight, but the first half was so bad it gave us next to no hope of getting back into the game. #lcfc
@Ashleypp1986: That fight and desire shown in the 2nd half is where the levels should be at from the off! That 1st half display was the worst I have ever seen in my 35 odd years of follwing the club! Fucking infuriating! #LCFC
@edward_w97: Silly game. Leicester’s first-half display is one of the worst I’ve seen from a pro team. Loads of subs, including Oliver Skipp at CB, and they end up not far off the comeback. Considering what #LCFC has achieved over the last 10 years, it’s crazy where they are now…
