Moyes admits they're showing relegation form after last night's defeat at Hull City.
"The performance was shocking and we all take responsibility for it. I've seen a few poor performances since I've been here but that will be up there with the worst of them," he told Everton's official website.
"It is up to the players to take responsibility but I take responsibility for the players I select.
"We could be dragged into a relegation fight - particularly because of the injuries and individual performances. But I am the one who has to take responsibility for the team. I pick the team and I sign them.
"I'm the one who has the ultimate responsibility."
