A former Premier League striker shared a series of images of himself and his son alongside Cristiano Ronaldo following a recent trip to Saudi Arabia.
The Al-Nassr captain assisted his side's opening goal as they handed Saudi Pro League leaders Al-Hilal their first defeat of the season on Friday.
Otavio's opener after just one minute at the Al-Awwal Stadium marked Ronaldo's 54th goal involvement in all competitions this season.
Prior to the game Ronaldo met with former Chelsea star Adrian Mutu, posing for a picture with the controversial striker and his young son, Tiago.
