Ronaldo says coach Jose Mourinho will always have his full backing.
"In football nothing surprises me. He is very good and is working very well, like the other goalkeepers. The substitutes are coaching decisions, the coach controls that and we have to respect his decisions," said Ronaldo.
On Mourinho's future, the former Manchester United star added: "It depends on his situation and that of the club. I would love it if he stays and the way he works is suited to a top club like this. I think he will stay, but I do not know. Everyone decides how they want to live their own life."
