However, Ronaldo hopes Mourinho will get Chelsea back on track, with the Premier League champions languishing 15th in the top flight.
"Mourinho's situation? I'm not surprised because in football anything can happen..." the Portugal captain told BBC Sport.
"Of course, he's a manager that I was working with for two years and I know his potential. I know that not just him but Chelsea are in this tough situation.
"As a Portuguese man, I want to see the Portuguese at the top level all the time.
"So this is what I wish for him that he can go through this bad situation and make Chelsea fans happy because they deserve it."Chelsea have already lost six of their 11 league games this term but bolstered their Champions League campaign with a much-needed 2-1 win over Dynamo Kiev on Wednesday.
