Chelsea have been described many times as a work in progress under Lampard - and this showed exactly why.
They have been vulnerable defensively all season but here at Goodison, with Everton inspired, all the flaws were on display.
Calvert-Lewin was the main beneficiary, taking advantage of chaos in the penalty area to score the Toffees' second, then striking again late on after Kepa compounded a poor clearance by letting the forward's his shot through his legs.
Chelsea can enter the market in January after their transfer ban was reduced to one window on appeal - and on this evidence Lampard will be spending a large part of his funds on stiffening a leaky defence.
