Cristiano Ronaldo's son, 'Cristianinho,' makes his winning debut for Portugal's U-15 national team.

Cristiano Ronaldo 's son, Cristiano Ronaldo Junior , aged 14, played his first match for Portugal on Tuesday, taking part in the Under-15 team's 4-1 victory over Japan in a tournament held in the Croatian town of Sveti Martin na Muri.

Wearing Cristiano Ronaldo's number 7 jersey, Ronaldo's son started the match on the bench and came on as a left winger during the second half, the same position his father played at the start of his career.

With Cristiano Júnior on the field (he played 26 minutes), the Portuguese team managed to maintain the lead they had gained, thanks to Rafael Cabral 's hat trick and Henrique Amen 's goal.

"Cristianinho," as he is known in Portugal, and his teammates will return to the field this Wednesday to face Greece and on Friday they will do the same against England, matches corresponding to Group B of the Vlatko Markovic International Tournament.

Cristiano Ronaldo Junior currently plays in the youth teams of his father's club, Al Nassr of Saudi Arabia , and previously played in the youth teams of Manchester United and Juventus of Turin .
