Carlo Ancelotti's side made a bright start at the Estadio de los Juegos Mediterraneos, with Ronaldo needing less than three minutes to break the deadlock.
There remained only one goal in it until after the hour mark, but then the floodgates opened and further strikes from Karim Benzema, Gareth Bale, Isco and Alvaro Morata sealed the rout, with the only worry for the capital club the fact Ronaldo had to come off at the start of the second half due to injury.
Ancelotti said: "I think it was a good game. We didn't concede any goals and that's important. The team all played well. We have to carry on this way because we are doing well right now. We've had a lot of problems because of international games and today has been a different game and we should be happy."
