Arsenal boss Emery saw his side’s hopes of a top four finish dealt a huge blow by Roy Hodgson’s slick Crystal Palace outfit on Sunday.
The Gunners went into the game knowing they needed three points to capitalise on defeats by Tottenham and Manchester United earlier in the weekend.
However, Arsenal slipped to a surprising home defeat at the Emirates with Christian Benteke, Wilfried Zaha and James McArthur giving the visitors all three points.
It was a frustrating day for the Gunners, who face difficult away trips to Wolves and Leicester in the next seven days.
And Emery should now sell three players in the aftermath.
The first of which has to be Shkodran Mustafi.
After the defeat to Palace, Emery did his best to talk up his struggling Arsenal defender by bizarrely saying: “He has been consistent.”
Consistently bad, perhaps.
There is currently a video doing the rounds on social media showing the Germany international making mistake after mistake this season.
Arsenal fans know that, despite being a World Cup winner, the former Valencia star is not good enough. Certainly not a patch on any of the centre-backs of eras gone before.
Emery should forget posturing and admit the player is not Arsenal-quality. If they can find a buyer, he has to be the first to go.
And Carl Jenkinson and Mohamed Elneny should be shown the door too.
Jenkinson, believe it or not, has been at the Gunners since 2011. That is eight years of below-par, damaging performances.
There was a spell a couple of years ago where it looked as if the 27-year-old would live up to his potential.
But the truth is that he has never looked worthy of being an Arsenal player.
The same can be said for Elneny.
The Egypt international, for a man so physically imposing, looks weak without the ball and nervy on it.
If Emery can find a buyer – something that may be tricky given how poor the midfielder has been this season – he has to cash in.
Their displays were so bad against Everton, Emery hooked Jenkinson at half-time, Elneny on 68 minutes and Mustafi may have followed had there been another centre-back on the bench.
Arsenal have had a good season. But, in order to make sure they improve next term, it’s time for Emery to get busy and cut Mustafi, Jenkinson and Elneny loose.
