Defender Conor Coady has admitted that Leicester's squad are in a "dark place" after their 4-1 thumping at Brentford.
Kevin Schade's first senior hat-trick and Yoane Wissa's leveller completed the Bees' comeback in west London on Saturday afternoon.
Facundo Buonanotte gave the Foxes a shock lead against the run of play, but the hosts raced into a 3-1 lead before half-time with Schade completing his treble just before the hour.
Defeat - a fifth in their last eight games - came in front of incoming new manager Ruud van Nistelrooy, who watched on from the stands.
