Chelsea interim manager Guus Hiddink says his players must look in the mirror after a very negative start to the season.
The 69-year-old will be in charge of the team when the Blues host Watford on Saturday afternoon.
And he wants to assess his team properly before deciding to add new players during the January transfer window.
"It is a different group of players [to when I was last at Chelsea]," Hiddink said.
"The players at that time were also big players and were leaders. We now have big players but it is difficult to compare.
"I talked to the squad yesterday and we talked about the past a little... why I am here, the reason why we are down.
"But I also told them things happen in football and I want everyone to look themselves in the mirror, for not just a second but for a long time.
"He [Eden Hazard] had a terrific season last year and it is normal that you get a little bit of a setback after that.
"I think he can be a key player as captain of a national team for Belgium. And he can be a key player here .
"It's the same with him, he has to be eager to perform.
"[January signings?] Let's go into the next few games and we will see. First, I would like to get through the first few games."
