Seamus Coleman acknowledged Everton "really let ourselves down" and must "look at ourselves in the mirror" following their spectacular late collapse against Bournemouth.

Sean Dyche's side, who were seeking their first points of the season, led 2-0 in the 87th minute at Goodison Park through goals from Michael Keane and Dominic Calvert-Lewin.

However, the hosts were undone by three crosses in the latter stages, with Antoine Semenyo pulling a goal back and Lewis Cook levelling, before Luis Sinisterra completed a sensational turnaround in the sixth minute of stoppage time. 

Boos rung around Goodison Park as the Toffees remained pointless and rooted to the foot of the Premier League table, and Coleman echoed the supporters' frustrations.

"We really let ourselves down in front of our fans," the skipper said. "We cannot take our foot off the gas at this level. Unfortunately, we did that.

"We cannot be conceding the goals that we did. We have to look at ourselves in the mirror."

Meanwhile, Dyche bemoaned the lack of responsibility amongst his players, as they became the first side in Premier League history to lose a game after leading by two or more goals in the 87th minute.

"We did so much right until they scored their first goal," the Everton head coach said. "The game should have been out of sight. We conceded one and then threw it away. I can't put my finger on it right now.

"They kept raining it forward and got their reward in the end. They were playing it forward and crossing it into the box, and we didn't deal with it. Simple stuff, but we threw it away. It is the third game we have thrown away this season.

"Everyone was looking at someone else to deal with things and that is when there is trouble. You could see the body language change. You have to see games through, and we have enough experience to do that, but today we didn't."

Bournemouth boss Andoni Iraola added: "It was the worst game we played this season. Everton deserved to win today, but the players kept pushing.

"I always have hope because this team has spirit. We have done it before and had some good comebacks. The spark of the first goal made us believe we could do it again."
