The Santiago Bernabeu side will have to deal with Borussia Dortmund in the semi-finals, while Barca were paired with Bayern Munich and Ronaldo expects both Spanish giants to progress.
"Madrid will make it to the Champions League final and so will Barca, although I think they'll have a tough time in Munich," the Brazilian told AS.
"I'll be in London for the final and I hope that Madrid win because I'm a Madrid fan."
Ronaldo also had his say on Lionel Messi and Cristiano Ronaldo and stated that the Argentine is probably the better player of the two.
"They're the best players I've ever seen. Perhaps Messi is slightly more complete, but they're both very good."
Messi has already netted 57 goals in all competitions for Barca this season, while Ronaldo has scored an impressive 50 goals so far.
