Nearly 5,000 supporters turned up to watch the Portuguese in action against the B team and were rewarded with a goal from their new star in the eighth minute.
Ronaldo broke the offiside trap to go clean through on goal before slotting his effort past the keeper. He then forced an error from defender Riccardo Cappellini who stabbed the ball into his own net three minutes later.
The 33-year-old was involved again when he set up Douglas Costa whose effort hit the post before he assisted Paulo Dybala.
Ronaldo didn’t emerge after half-time and the first team won the game 5-0. Watch his excellent finish in the video below.
