Gary Lineker admitted Leicester City's first-half performance against Nottingham Forest capped off a "horrific" few days and branded the display a "debacle".
The Foxes were stunned by the rampant Reds in the opening 45 minutes as Steve Cooper's side raced into a three-goal lead.
Philip Zinckernagel tapped in from close range before Brennan Johnson made it 2-0 just a minute later with a composed finish through the legs of Danny Ward.
