Everton manager David Moyes admits his side's current form is a worry after they were held to a goalless draw at home to Wigan.
The home side created the majority of the chances but the closest they came was when Marouane Fellaini headed over in the first half and Tim Cahill hit a post in the second.
Wigan defended resolutely and almost snatched a late winner when substitute Ronnie Stam's shot was turned around the post by Tim Howard. But Everton have now not won in seven games and Moyes admits their failure to take their chances is affecting the players and the fans.
"It certainly wasn't their attitude. I questioned it a bit in the last home game against West Brom (a 4-1 defeat) but they went for it today," said the Toffees manager.
"They were industrious without having the quality required but we just missed chances. I don't think you get better chances in the Premier League than we did today - three or four opportunities. The longer we didn't take them the more frustrated we got and the more anxiety came into our play and the crowd. We just have to take those chances.
"The crowd know we have been here before in a similar situation but I think the worrying thing is we are not beating teams at Goodison who, over the years, we have done."
