Chelsea boss Jose Mourinho has admitted that he is confused by the poor atmosphere inside Stamford Bridge during his side's matches.
The Portuguese was critical of his side's supporters in the aftermath of the Blues' win over Queens Park Rangers on Saturday, claiming that playing at home was like playing in an "empty stadium".
"We are the team to get less support in home matches. When compared to my previous time I think it's getting worse," Mourinho told reporters.
"I don't question the passion and the love - I'm nobody to question that and I know clearly that is not true.
"I will always love them and respect them, but I don't know [why the atmosphere is poor]."
Chelsea lead the Premier League by four points after 10 matches this season.
