The Blues lost at home for the second game in a row and the coach feels they have to be better against well-organised teams
Frank Lampard says his team must get better at breaking down their opponents after they suffered another home defeat on Boxing Day.
The Blues went down 2-0 at home to Southampton on Thursday thanks to goals from Michael Obafemi and Nathan Redmond.
The loss is Chelsea's second in a row at Stamford Bridge and they have won just two of their last seven matches in the Premier League, though they beat London rivals Tottenham away last week.
