Cristiano Ronaldo’s eldest son made his on-field debut with Portugal’s under-16 national team on Thursday.

The 15-year-old Cristiano dos Santos, often referred to as Cristianinho, came off the bench in the 90th minute as Portugal secured a victory with a score of 2-0 against Turkey during the Federations Cup tournament being held in Turkey.

Previously, Cristianinho, who is part of the youth academy at Al-Nassr in Saudi Arabia—his father’s current club—had been selected for Portugal’s U-15 squad.

Portugal’s next matches in the tournament will feature confrontations against Wales and England.
