Former Chelsea defender Mario Melchiot believes Jose Mourinho's team is over-reliant on Eden Hazard.
Melchiot says Chelsea can become unbalanced with Hazard so prominent.
He explained: "When the ball comes to Hazard, then everyone in the Chelsea team rotates.
"I'm a big fan of Eden, but it's not only about him at Chelsea.
"There lacks balance in the team because the right one should ensure as much danger as Hazard."
