After Frank Lampard seemed to finally have got his Everton side out of their rut, with a comprehensive win against Crystal Palace and a solid draw on the road to Fulham, a travelling Leicester City saw it all come crashing down.
The stubborn Foxes executed their game plan to perfection and snuck in front shortly before the break following a Youri Tielemans stunner.
His volleyed strike left Jordan Pickford rooted, and as the Toffees pushed forward in search of an equaliser in the second half, Harvey Barnes sealed the three points for Brendan Rogers.
Arguably, under Goodison Park floodlights, the midfield was massively culpable for this result, as the usually workmanlike trio of Idrissa Gueye, Alex Iwobi and Amadou Onana disappointed.
The latter, in particular, offered an invisible performance despite his hulking frame and seemed to drift in and out of the proceedings.
James Maddison was also afforded far too much space throughout the game, resulting in his two assists for Leicester’s goals.
With a man like Onana, whose whole game focuses on tackles, to not make a single one all game is a searing indictment of his performance.
He would also lose 50% of his duels, compounding his defensive weaknesses.
Lampard clearly felt let down too by Onana, as he dragged him off after just 61 minutes in a like-for-like switch for Abdoulaye Doucoure. The Frenchman did not offer much more but was only eight touches short of his tally despite playing just 29 minutes.
With youth on his side and a bright future laid out performances like this will not worry Evertonians. His ceiling remains immensely high, and the 21-year-old will have to suffer to become a success one day.
He will be hoping that these nights are few and far between, as will his manager.
