Hazard, along with many of his Chelsea team-mates, has struggled to find consistent form so far this season, with the Blues having slumped to four defeats in their opening nine Premier League games.
The Belgian playmaker – last season’s PFA player of the year – has yet to find the net for Mourinho’s men this season.
Hazard played the full 90 minutes as Chelsea were held to a goalless draw by Dynamo Kyiv in the Champions League on Tuesday night.
However, Mourinho remained coy when quizzed about whether Hazard is set to start Chelsea’s clash at Upton Park on Saturday.
Mourinho told a news conference on Friday afternoon: “I don’t know [if Hazard will start].
“He played the last match and played for 90 minutes and he was part of the compact team that kept that clean sheet.
“I’m happy with his contribution against Dynamo and that’s it.”
Hazard, 24, has featured in all nine Premier League games for Chelsea so far this season and has notched up two assists for his team-mates.
