Chelsea boss Jose Mourinho has warned his players that no-one's place is guaranteed.
Speaking on Chelsea TV, Mourinho said: "Everybody is intelligent enough to understand that we play around 60 matches a season - and no one plays 60 matches.
"If you are not first-choice at the beginning of the season you know that, step by step, you will get matches.
"We need rotation but players know chances will be here for them."
