Ronaldo's hat-trick on Saturday - his 20th for Real - began with a left-footed strike following a mesmerising step-over.
After pouncing on a mistake from visiting defender Federico Fazio to make it 3-0, he then launched a rapid counter-attack with a 50-yard run that ended with him tapping in a Gonzalo Higuain pass from close range.
