The 38-year-old, who is on a £177million-a-year deal at Al Nassr, helped his side beat Iceland 2-0 in their final Euro 2024 qualifier on Sunday night.
It was Portugal's tenth straight win in qualifying with the Euro 2016 winners triumphing in every game under Roberto Martinez's tutelage so far.
Following the full-time whistle, Ronaldo gave his shirt away, but was left feeling rather cold as he showed off his impressive physique.
Thankfully for the Manchester United legend, ex-Wolves goalkeeper Rui Patricio was on hand to save the day.
The Roma shot-stopper, who was an unused substitute, was filmed taking off his jacket to give to the five-time Ballon d'Or winner.
