Chelsea boss Jose Mourinho has refused to reveal whether Eden Hazard will return to his starting XI for Tuesday's Champions League clash against Dynamo Kiev.

Hazard, 24, was voted the Premier League's best player last season as he played a key role in the Blues finishing first in England's top flight.

The Belgian has struggled for form this season, however, and was dropped for Saturday's clash with Aston Villa – a game that Chelsea won 2-0.

At a press conference, Mourinho was asked whether Hazard would return for the European clash in Kiev, but the Portuguese refused to give a proper answer.

"Last season, he had a phenomenal season. I won't tell you if he will play.... [Dynamo] won't know," Mourinho told reporters.

Hazard has not yet scored in nine league games for Chelsea this season.
