Speaking to the media, Slot said: "[Complacency] is the last thing. There's no reason for us to be complacent because we're not winning every game by three or four goals.
"It takes us so much effort and hard work combined with quality to win games of football but the team (Manchester City) that won the league the last four seasons were already 3-0 up at half-time in a lot of the games they played.
"That's not the way it is for us. We're fully aware that we have to compete for seven more games. Wednesday (against Everton) was a close call. This was a close call. Many times we've been on the right side, but we were on the wrong side, and that's mainly because of the errors we made."
