All of Chelsea's key players are fit as they put their unbeaten record on the line once again this weekend.
It means that Diego Costa is ready to play despite picking up a knock in the 5-0 win over Schalke in the week whilst Ake continues his recovery from a hamstring injury.
The Blues boss seemed to rule out any notion of rotating his side during this busy schedule of fixtures as they put their unbeaten record on the line, looking to make it 13 games without defeat in the league so far this season.
It may not be good news to some players who might wish to get some more game time, but Mourinho has praised those players and is confident that if they're called upon, they will be ready to step in.
He told reporters: "My 'untouchables' are the ones who aren't playing, they are responsible for what we are doing. They are all ready to help.
'"For us every competition is important so we don't rest players and we try to play with our best team.
"We've improved where we can without worrying about other factors and other teams."
After the win over Schalke, which secured Chelsea's passage to the knockout stages of the Champions League, Cesc Fabregas said he feels that he is playing the best football of his career, which evidently delights the Chelsea boss.
Mourinho added: "If Cesc Fabregas says he is playing the best football of his career that means something. You can see it in his body language."
