Terry believes the Blues are the only club in the Premier League in a position to pick up 90 points.
Terry said: “We should be further ahead at the top of the league and we only have ourselves to blame.
“I understand everyone feeling frustrated, our defending of set-plays was unacceptable.
“We’re still on target for 90 points this season and we are the only club which is.
“Saturday (3-3 draw with Everton) was the first time we have dropped points at home this term and I want it to be the last.”
