Jurgen Klopp has said Liverpool were denied a "100% penalty" and questioned what VAR official Stuart Attwell "had for lunch" after Alexis Mac Allister was subjected to a 99th minute chest-high challenge by Manchester City's Jérémy Doku in Sunday's 1-1 draw at Anfield.
Mac Allister's second-half penalty, following a foul by City keeper Éderson on Darwin Núñez, earned a point for Liverpool after John Stones had given the champions a first-half lead.
But Liverpool could have been given the chance to win the game deep into stoppage time had referee Michael Oliver been asked by VAR official Attwell to review Doku's challenge.
