Cesar Azpilicueta admits that Chelsea can't afford to keep conceding such high numbers of goals if they want to achieve anything this season, as they begin their Champions League campaign against Sevilla on Tuesday night.
Chelsea go into the match having conceded three goals for the second time this season, as Southampton earned a deserved point at Stamford Bridge at the weekend with a late equaliser.
It is just the latest defensive mishap after the Blues conceded a record 54 goals last season, the most since Roman Abramovich bought the club in 2003.
