Chelsea boss Jose Mourinho admits he's yet to settle on his best XI.

Mourinho has challenged his players to provide him with the answer.

"Of course, I don't know [what my best team is]," he said. "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."
