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.
Louis Saha, three times, and Seamus Coleman both had opportunities to score but could not break the deadlock.
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.
"I am saying 'Is is something else other than just not scoring goals?' and I am finding it hard to look further than that.
"It wasn't just the centre-forward today, there were chances shared around the team and no-one converted any of them.
"The anxiety is coming from the form and our position (two points above the relegation zone).
"We are all wondering where we are going to score a goal.
"I tried to freshen things up with 20 minutes to go and I thought we were worse then than at any time in the game.
"I thought we looked more open and a poorer team and I thought my substitutions today were poor and I made the wrong choices."
Steven Pienaar limped off with a groin injury but could easily have been sent off in the first half after a late tackle on Hendry Thomas, with the Honduran also benefiting from the leniency of referee Mike Oliver.
"He was possibly lucky to stay on," admitted Moyes. "There were a couple of challenges which could have gone against us."
Wigan boss Roberto Martinez praised Oliver for his handling of a scrappy game.
"I felt he kept a good degree of consistency because if I am honest with you Hendry Thomas had a yellow card and then made another challenge card and I've seen yellow cards come from that," he said.
"Pienaar's was a really late challenge but I think you have to give credit to the referee because it was a difficult game to manage."
Martinez was impressed with his side's defensive display and even felt they should have snatched victory at the end.
"When you come to Goodison you need all your players to be concentrating and on top of their game and I think (goalkeeper ) Ali Al Habsi had two or three moments when he showed his quality," added the Spaniard.
"I felt we finished the stronger side. In the first half Everton got a very good momentum and were winning territorial advantage and we just needed to defend well with a lot of composure.
"The performance was what we had to do and was what was needed to get a positive result but in the manner we finished the game I feel we dropped two points."
