The Portugal international scored twice on his first appearance of the season for Manchester United against Newcastle United as he helped to fire the home side to a 4-1 win at Old Trafford.
Ronaldo is settling into life back at Old Trafford 12 years after he left the club to sign for Real Madrid in the summer of 2009.
