Talks have yet to take place regarding new deals for the experienced trio, but Mourinho has revealed that everything is "very calm" behind the scenes at Stamford Bridge.
The 50-year-old told Sky Sports News: "Their desire to play for this club, nobody has doubts about it. We want them to feel free to express and to enjoy these last years of their careers.
"Everything is very calm and at the end of the season, probably before that, the club will sit with them, and the offer will be on the table."
Mourinho had already stated this week that Cole would be offered a new deal, despite falling out of favour over the past two months.
