Interim Chelsea boss Guus Hiddink believes Eden Hazard needs to rediscover his self assurance to recapture his Chelsea form of last season.

The 24 year old faced fierce criticism for his performances this season, with some Chelsea fans making a banner describing him, Diego Costa and Cesc Fabregas as "rats" in the aftermath of the Jose Mourinho sacking.

"He had a terrific season last year and it's also normal you can have a setback after that," said Hiddink.

"But I think he can be a key player again.

"He is a key player as captain of the national team in Belgium - but also here when he gets back into shape.

"He was unlucky to be injured recently, which was another setback.

"We need to get the ego back for him to perform."
