Cristiano Ronaldo 's son, Cristiano Ronaldo Júnior, scored his first two goals for Portugal 's under-15 side in Sunday's 3-2 victory against Croatia .

The result allowed Portugal to win the Vlatko Markovic international tournament that was played in Croatia this week.

In just his fourth appearance for Portugal's U15 side , the Al Nassr academy forward started and struck the opener in the 13th minute with a beautiful left-footed finish.

The 14-year-old, wearing the No. 7 jersey, then copied his father's famous "SIU" celebration.

He added his second before half-time with a close-range header before being replaced in the 54th minute.

Portugal's Football Federation celebrated Ronaldo Júnior's goals by writing on Instagram: "The first SIUUUU of Cristiano Jr. for Portugal!"
