Ronaldo played a preseason high of 80 minutes at Yankee Stadium in New York.
"I understood that the stadium was also demanding that [that Ronaldo plays more minutes]," Mourinho said afterwards. "A historical stadium. A historical opponent. Full stadium. Great support.
"The best way to promote the game is to play like we did tonight.
"And I think Cristiano was part of the show. He's a part of what the people want to see.
"There was lots of magic here, and I think we did what the stadium deserved and what Yankee history deserved and what the people deserved because it was magnificent.
"If I have this kind of crowd, so enthusiastic crowd in the Bernabéu, I don't lose a match in the Bernabéu. The people are fantastic, enjoying, supporting and reacting to the great [plays]. And so I just love it."
