Frank Lampard has admitted that the Chelsea squad are no longer the force that they once were.
The Blues are currently fifth in the Premier League table, some 20 points behind joint leaders Manchester City and Manchester United.
Having recently drawn 0-0 with Tottenham Hotspur, Lampard believes that improvements are needed if the club are going to secure Champions League football for next season.
"The fixtures and where we are in the table doesn't lie - we're not as good as we used to be," Lampard told the club's official website. "We used to have a fortress here and, for whatever reason, we're just not doing it. It's something we must all put right.
"You know a derby against a very good Tottenham side is going to be tough. But I don't think we were at it enough. We had to play more with the urgency we showed against Napoli.
"Against Tottenham, we didn't really do enough to lift the fans."
Chelsea take on Benfica in the Champions League tomorrow night.
