The Portuguese boss is expected to give fringe players a chance against Swindon Town in the Capital One Cup, with Juan Mata likely to feature after struggling for minutes this term
Chelsea manager Jose Mourinho has admitted he does not know what his strongest side is and has called on his players to make up his mind.
The Portuguese returned to Stamford Bridge in July for a second spell, but has seen his squad struggle for consistency during the opening stages of the season.

"Of course, I don’t know [what my best team is],"Mourinho told reporters. "But the players have to give me the answers. I cannot dig and dig and dig looking for the best team. The players must give me the answer.
"Do I have a doubt that [Branislav] Ivanovic is in this moment my right-back? I have no doubt. You see the way the guy performs. So it is up to them.
"If somebody is waiting for me to give shirts because of status and history, that’s not the point. Of course, I have some doubts in some positions and I think it’s normal."
