Sam Allardyce pointed to wasteful finishing from his team in the wake of an away defeat, this time at Burnley where Everton threw away a 1-0 lead to lose 2-1.
Goals from Ashley Barnes and Chris Wood turned the match on its head in the favour of Sean Dyche's men in the second half but Allardyce felt that the game could have been put beyond the Clarets before half time.
The manager made a similar argument last week following the defeat at Watford, a game in which the Blues created very little but this time he had a stronger case.
Everton could have scored two or three in what was a promising first-half display overall but had to be content with the one they did fashion for Cenk Tosun.
Theo Walcott spurned a couple of chances and Tosun had a low shot saved as the Toffees looked capable of ending a five-match losing streak away from home.
But Dyche retooled at half time and Barnes levelled 10 into the second half and Wood scored the winner with an unchallenged header from a corner with 10 minutes to go.
“We lost it by not scoring the second goal when we had the clear, clear opportunities — more than one — as well as the goal we scored,” Allardyce said afterwards.
“I think with Burnley not having won in 11 matches and if we'd gone 2-0 before half time, it would have made it hugely difficult for them.
“And then gifting a goal 10 or 11 minutes into the second half lifted the whole spirits around Burnley's ground and then there's more pressure ourselves and a goal that could have been avoided.
“Really the second half performance… we didn't make the right decisions both defensively and certainly in possession so we had to defend deeper than we had to in the first half.
“And when we did get into the game after we'd soaked up that pressure, we failed to get in front or get the opportunity get in front and it was very unfortunate that Gylfi carved out such a brilliant opportunity for himself but didn't finish it off and then we pay the price for that.
“Losing a goal from a corner is something I always dislike and could have been avoided so two very easy goals gifted to Burnley today which takes the pressure off them not having won in 11 and heaps the pressure on us and that's five defeats on the trot.
“So while our on form and our own points [tally] is good, we were simply just not good enough today, yet again, and I'm very disappointed.
"I feel worse than the fans — they won't believe this — but it's my responsibility," Allardyce continued, although he smirked when it was suggested to him that his decision to replace Gylfi Sigurdsson with Yannick Bolasie late on was met with boos from the travelling fans. "I go home and say to myself 'how do I put this right?'
"For me to see the players under-perform in the second half is very disappointing for me. It's my problem to sort it out."
