Both sides have dreams of Champions League qualification, and with Liverpool again slipping up there are now four clubs on 39 points with the Anfield men clinging to fourth spot only on goal difference.
And it is City who are beginning to slip. They are now down to seventh having held a top four spot for much of the season, and their manager was disappointed with their approach at Goodison Park.
After seeing Joleon Lescott grab Everton's winner, Eriksson said: "It took far too long for us to get going, we started 40 minutes late. Just the last few minutes of the first half saw us starting to play the football we want to play.
"We were kicking long balls, chasing second balls, we are not good at that. If that is the way we are going to play our football we will have to sell half our team and buy other players instead.
"We will not do that. So it was frustrating and disappointing, we were not brave enough to play the way we wanted in the beginning.
"It was more our attitude. Joe Hart kicked the ball out more than 18 times in that first half, long balls going nowhere and we are not good at that.
"In training it is forbidden. So why did we do on Saturday something different to the way we play in training all week?"
He added: "But credit to Everton. They are aggressive and our opponents know we want to play football and they try to prevent it.
"We have to be big enough to beat that if we want to be a great team. But we were more positive in the second half, our attitude was much better.
"But we did not create enough chances. Considering how much we had the ball, we should be creating more opportunities than that. But it has been our problem in many, many games this season."
