Manchester City manager Roberto Mancini blamed himself for his side's potentially damaging defeat at Everton.
The Italian conceded he had been complacent having watched his side's three-point lead at the top of the Barclays Premier League get wiped out following a 1-0 defeat at Goodison Park.
Former Manchester United midfielder Darron Gibson, whose old club now trail the leaders only on goal difference, scored the only goal of the game on the hour and Mancini said: "I didn't prepare well for this game. I thought it was maybe easier. I know here it is never easy, never."
