Former Chelsea boss Ruud Gullit believes Antonio Conte's team have failed to build on last season's title triumph.
The Dutchman has outlined why he believes things are going wrong for Chelsea this term.
Gullit told beIN SPORTS: "When you win a title, things change. The opposition is more alert.
"Plus the fact that there's the Champions League. There's a lot of things to play for. You have to divide your team in a manner that a lot of players can play.
"Chelsea also had a lot of problems [over the summer]… I think they sold some good players - [Nemanja] Matic, [Diego] Costa - and it has been difficult to replace them."
