This was a stunning way to remind Liverpool how swiftly their invincibility has slipped this season, and as they were demolished with three Leicester City goals in seven minutes it was hard to see how Jurgen Klopp might put them back together again.
An astonishing climax to a gripping match saw Brendan Rodgers inflict a defeat on his Anfield successor that looks terminal for whatever might have remained of their title defence. In that period of disintegration, Klopp turned to argue with the Leicester entourage in the stand behind him at an otherwise empty King Power, Jamie Vardy strummed a guitar-substitute corner flag in celebration and the close-ups on Liverpool faces were pure dejection.
This is five defeats in the last ten Premier League games for the reigning champions, and this latest the third on the spin for a team that cannot find its confidence again. There were other earlier chances for Leicester and Vardy in particular that hinted at the storm brewing and they came from Liverpool problems that will not be simply fixed. There was a debut for the January signing Ozan Kabak who has walked into a club in crisis and brought his own uncertainty to the chaos, and that was not the only problem.
The midfielder Thiago Alcantara, an early replacement for the injured James Milner, had a lamentable afternoon and there was not a great deal to build-up the confidence of the goalkeeper Alisson. For Leicester, though, the opposite was the case: they moved up to second place in the Premier League and their fast-breaking, lightening quick forward line are a joy to watch.
They came for Liverpool in the last 20 minutes, first of all denied a penalty by Var when Thiago was adjudged to have fouled the outstanding Harvey Barnes just outside the area. James Maddison whipped in the free-kick which appeared to elude all, even the lunge of Daniel Amartey, and rested in the corner of the goal. Another Var check for offside, another wait, but Leicester were level.
It had taken Liverpool 67 minutes to open the scoring when a brilliant set from Roberto Firmino had created the space for Mohamed Salah to shape a shot around Kasper Schmeichel. Yet Leicester, after an early siege, had looked good and they came back with that Maddison equaliser, Vardy pounced three minutes later when Kabak and Alisson converged on the same throughball and the defender pushed away from them both.
The young Turkish defender from Schalke was beaten again moments later by Barnes after the excellent Wilfred Ndidi had won possession again in midfield from a careless Liverpool. They are ten points off Manchester City now having played two games more, and with every game, the vulnerability in defence seems to be more pronounced. More injuries to Fabinho and the new recruit Ben Davies beg the question where they go from now.
