Everton 's misery was compounded in a 2-0 defeat to Leicester in David Unsworth's first Premier League game in charge since Ronald Koeman's sacking.
Jamie Vardy finished a lightning fast counter-attack for the Foxes before Jonjo Kenny's embarrasing mis-kick found its way into the back of the net.
The Toffees' caretaker manager, who once again left out Davy Klaassen to raise more eyebrows, attempted to find a route back into the game by sending on Oumar Niasse.
It was to no avail though as the Foxes stood firm and gave their fans optimism for the weeks and months ahead under Puel.
Here are the five talking points from the King Power:
1. Unsworth running out of time to convince
Tactically, David Unsworth got it wrong in the first half, with a traditional 4-4-2 formation that simply gifted Leicester's lightening quick attacking players space on the break to exploit.
They didn't need much of invitation to be fair, with Demarai Gray in particular revelling in the lack of protection offered to veteran Leighton Baines.
2. Unsworth makes point with Mirallas change
It was no surprise the caretaker manager hauled off both his wingers at the interval, because neither – and Kevin Mirallas in particular, understood the role they needed to play in reducing the space their opponents had to operate in.
It is all very well giving them a chance they were denied under the previous manager, but sometimes there is a reason for that.
It is the same with Jonjo Kenny at full back. He is a real talent, but exposing him too soon is a risk...and he looked shell-shocked here.
3. Back to basics for Puel
Giving the home side so much space, allowed new boss Claude Puel to show he understands how Leicester operated when at their best: ie; winning the title!
He went back to virtually the title winning defence, and used that defensive solidity to spring counters using the pace of Vardy, Mahrez and the brilliantly effective Gray. It's not rocket science, but that formula seemed to have been forgotten over the past year.
4. Puel looks keen to entertain
Puel has been accused of being boring...and eight home games at Southampton without a goal certainly back that up.
But here, Leicester looked dynamic and full of adventure, even if they were given a helping hand by a naïve Everton system.
Puel was a slightly risky appointment, but his track record is good, he is a tactically aware coach, and he knows a decent player when he sees it. Whether his personality can match is the question.
5. Manager dilemma on display
Sacking a manager at this stage of the season always leaves a hole that is difficult to replace – and in Puel and Unsworth you have two sides to the same problem.
Top managers generally aren't available mid season, so you can end up with either the risk of inexperience, or the alternative of steady but rarely inspiring and imaginative.
Leicester will probably avoid any relegation fears under Puel, but Unsworth may be a top coach in the making...possibly.
It will be interesting to see who gets the better of the bargain with the devil.
