Everton boss David Moyes has admitted he is concerned by his side's erratic start to the season after Saturday's 2-0 derby loss to Liverpool marked their third home defeat of the campaign.
The Toffees conceded two second-half goals to Fernando Torres in quick succession and then had salt rubbed into their wounds with the late sending off of Tim Cahill.
"Our start does worry me," admitted Moyes. "It is the same group of players, in the main, who finished fifth last season.
"Our performances have not matched that. Sometimes you cannot find the winning formula, so it is my job to sort things out.
"Maybe you can see the difference £100million makes to a team, but I expect my team to compete. And for most of the game they did."
Meanwhile, Moyes questioned the decision of referee Mike Riley to show Cahill a straight red card for an 80th-minute tackle on Xabi Alonso.
"I have had a chance to look at and I don't see a red card tackle, I really don't," he told the club's official website.
"I see a yellow card and I don't think it was the worst tackle in the game today.
"I think we were all really surprised it was a sending off."
