Everton, laboring under intense pressure after two league losses, briefly enjoyed a 2-0 lead over Bournemouth in a seven-minute spell after break-through goals from Michael Keane and Dominic Calvert-Lewin.
Bournemouth had been laboring most of the game on the back foot, but with three minutes left they managed to pull a goal back when Antoine Semenyo poked home from close range.
Added time saw Lewis Cook’s powerful header finding the back of the net and Luis Sinisterra breaking Everton hearts with the winner to leave the hosts rooted to the bottom of the table, booed boisterously by their own supporters at full time.
After leading 2-0 goals until the 87th minute, Everton’s defeat was the latest a team has ever been two or more goals ahead in a Premier League game they have gone on to lose.
“We really let ourselves down in front of our fans,” Everton captain Seamus Coleman said.
“We cannot take our foot off the gas at this level. Unfortunately we did that. We have to look at ourselves in the mirror.”
