Leicester capitalised after being presented with some gifts from the Everton back-line and summer signing Funes Mori has taken most of the blame.
The Argentine defender was guilty of giving away a penalty early on in the contest, and he never looked comfortable after that mistake.
Funes Mori actually made a bright start to his Everton career, but his performances in recent weeks have raised question marks over his quality.
The 24-year-old has come into Everton’s first-team to cover for the injured Phil Jagielka, but he has failed to make the step up thus far.
The Toffees have leaked goals since Jagielka was sidelined, and Everton fans appear to be hoping that the England international comes back to fitness soon.
Here is the best reaction from Everton fans on social media site Twitter to Funes Mori’s latest performance.
Its gotten to the point that I get nervous anytime Funes Mori touches the ball #EFC— Josh Babcock (@jbabs822) December 19, 2015
So how good actually are john stones and Funes Mori? Our goals conceded says not that good actually.— Ham Ez (@JS_EFC) December 19, 2015
Funes Mori is average as well. The quicker Jagielka is back the better #EFC— Sean Comer (@ComerS88) December 19, 2015
@MattJFootball stones and funes Mori have been awful the last few games they look like they can be got at the pair of them— County Road Blue (@fredyallan45) December 20, 2015
@philmcnulty completely agree Phil. As well as Funes Mori has adapted he doesn't look up to it. Jagielka couldn't come back soon enough— Tom Wilkins (@bluetom79) December 20, 2015
