Manchester City manager Sven-Goran Eriksson accepted that his side had deserved nothing from their home clash with Everton, which ended in a 2-0 defeat for the Citizens.
City lost ground in the race for a European spot as they failed to build on their derby success at Old Trafford last time out, leaving Eriksson with no complaints.
He told the club's official website: "We have been brought back down to earth after beating United, but I thought we did well in the first 30 minutes.
"This was a real disappointment, we did not play that badly and had a lot of possession without getting any penetration.
"We tried hard in the second half, but with our attacks they were able to break and still create chances. Of course Everton are a strong team, well organised and they defended very well."
Meanwhile, Eriksson felt that referee Rob Styles acted in haste in showing Martin Petrov a straight red card for aiming a kick at Leon Osman late on in the game.
The Swede added: "I thought it was very harsh. The player backed into him and he flicked his boot at him.
"The Everton players seemed surprised he was sent off, but he got it and that's it.
"It needs more than just a word from me with Martin now, because we lose him for three games and that is hard for us."
