Everton were hammered 3-0 at Bournemouth in the Premier League to stretch their run of games without a win in all competitions to four.
They were soundly beaten by the same opponents 4-1 in the Carabao Cup in midweek and lost 2-0 to Leicester City in an insipid display at home the previous weekend.
Their only win in their last eight games was the 3-0 dismantling of Crystal Palace but, considering the remainder of the run includes just one draw and six losses, it's clear that the Palace result was an execption rather than a sign of improvement.
The woeful run of form has seen Lampard's odds of being the next Premier League manager to face the sack cut to 1/2.
Things aren't much better for David Moyes at West Ham after the Hammers were beaten 2-0 at home by Leicester City on Saturday.
They were also embarrassingly knocked out of the Carabao Cup on penalties by Blackburn in midweek.
The Scotsman's odds of losing his job are 7/2.
Those two are by far and away the favourites with the rest of the top candidates all well behind, at least in terms of odds, with Jesse Marsch next at 9/1 and Steve Cooper at 11/1
Tottenham Hotspur's Antonio Conte seems to have bought himself a bit of breathing room with a last-gasp and highly dramatic 4-3 win over Leeds United to see his odds lengthen to 14/1.
