Sam Allardyce was scathing of his team's inconsistency and what he described as a “pathetic” first-half display following today's 5-1 thrashing at the hands of Arsenal at the Emirates Stadium.
Aaron Ramsey scored a hat-trick and there was a goal, allowed despite a clear offside, for Gunners debutant Pierre-Emerick Aubameyang as Arsene Wenger's side racked up five goals against the Toffees for the second time this season.
Dominic Calvert-Lewin came off the bench to score a consolation goal to make it 4-1 as Everton improved after the introduction of Tom Davies for the hapless Michael Keane at the interval but Arsenal's fifth underlined the paucity of the visitors' defending.
Allardyce, who vowed that the kind of defensive capitulation he witnessed against Tottenham last month couldn't happen again, watched on from sidelines as his defence opened up again for Ramsey to complete his treble.
He expressed his anger and "bitter disappointment" to evertontv after the match and suggested that the performance made it look as though he and his staff were not doing their job properly.
“The first half was a disaster,” Allardyce told the cameras. “I have a lot of trouble with the players [not] taking onto the pitch what we actually asked them to do.
“The consistency level has always been a worry since we had that little burst when I got here with the fact that we could perform at that level like we did on Wednesday night against Leicester and then dip so low in the first 45 minutes against Arsenal.
“That is a big worry for me. I have to say, the longer I go on, the players are showing so much inconsistency that I have to face the uphill battle of trying to get them to be more consistency and to perform at their best level, week in and week out.
“It's no good playing okay in the second half, getting the goal and trying to make the score look respectable. It's far too late. It's just a pathetic first-half performance.
“We studied how Swansea played and we set out to play as [they] did because they had a fantastic victory [over Arsenal] in midweek but obviously we didn't put that game plan into the manner that Swansea did.
“At the end of the day, I can pick as many systems as I want to pick but if a player plays like they did today — and I'm talking about all 11 in the first half — then you've really got no chance. Tactics and systems mean absolutely nothing.”
