In the eight games since Klopp piled the pressure on, Chelsea have picked up just seven points, losing five times.
It’s a run of form that has seen them drop from the summit, to perilously close to the bottom half.
In that period, only rock bottom Sheffield United have been beaten on more occasions, with their defensive frailties exposed once again vs Leicester City.
“Where everything was rosy in mid-December, it is not so now,” Lampard said after the defeat at the King Power.
He admitted that some of his players may have thought they had cracked it when times were good.
Klopp may have believed that too…either way, they now look a long way away from a team anyone is backing to lift the trophy come May.
