The 36-year-old left Juventus last weekend heading for Manchester City but some Red Devils legends including Sir Alex Ferguson and Rio Ferdinand changed his mind.
Meanwhile, Mourinho was asked about the five-time Ballon d’Or’s return to United during his prematch conference over the weekend as reported by Goal.
He said “The only thing I say and it seems basic and logical to me, if Juve are happy, if Cristiano is happy and United are happy, then it’s the perfect business. There’s no need to talk about Cristiano. For 20 years he has written history, there’s nothing to comment.”
