Speaking to Sky Sports reporters ahead of tonight's Champions League clash with CSKA Moscow, the 27-year-old claimed his Portuguese compatriot has no plans to leave Spain.
"Mourinho will stay with Real Madrid next season," said Ronaldo. "But it is the club that is the most important thing and not Mourinho, or me."
Following the Stamford Bridge sacking of Andre Villas-Boas less than a fortnight ago, Mourinho has been installed as the favourite to replace him at Chelsea - a move that would reunite him with Blues owner Roman Abramovich.
Mourinho celebrated his 100th game in charge at Real in Sunday's 3-2 La Liga victory over Real Betis, but after frequent reports of growing unrest at the Bernabeu, the 'Special One' had been earmarked for a return to the Premier League.
With Harry Redknapp poised to leave White Hart Lane for the England manager's job, Mourinho has also been linked with Spurs, but the recent Chelsea vacancy has pushed the north Londoners further down the pecking order.
Speculation last week suggested that the Portuguese tactician would demand £12million a year in salary, plus the addition of Ronaldo, in order to convince him to return to west London, but the former Manchester United man has also denied those rumours.
"The club is always growing season after season," he continued. "At Real Madrid I have continually improved in order to compete with my team-mates.
"It is important for me to be always learning and I want to continue to do my best, which is why I am very happy."
