Portugal captain Cristiano Ronaldo believes his eldest son, Cristiano Ronaldo Jr., has the potential to surpass his achievements in football, revealing that the teenager is already physically ahead of where he was at the same age.

The five-time Ballon d’Or winner made the remarks in a video shared by Netflix Sports while watching his 16-year-old son train with the Al Nassr youth team.

Ronaldo, who continues to play at the highest level at the age of 41, said Cristiano Jr. has developed into a bigger and stronger player than he was as a teenager and expects him to continue growing physically.

“He’s a good kid. The other ones are tougher, the ones at home, the small ones. This one is no problem,” Ronaldo said.

“When I was his age, he is a little bit bigger and stronger. I was smaller. I think he will be bigger than me.”

Cristiano Jr. has attracted increasing attention in recent years as he follows in his father’s footsteps, progressing through youth football while training with Al Nassr’s academy in Saudi Arabia.

Despite praising his son’s physical development, Ronaldo stressed that size and talent alone would not be enough to guarantee success at the highest level.

The former Manchester United, Real Madrid and Juventus star noted that dedication, discipline, hard work and the right mentality would ultimately determine whether Cristiano Jr. could fulfil his enormous potential.

As the son of one of football’s greatest-ever players, Cristiano Jr. continues to face high expectations, but Ronaldo has consistently emphasised that he wants his son to enjoy the game and carve out his own path rather than live in the shadow of his famous father.

With the youngster continuing his development at Al Nassr, football fans will be watching closely to see whether he can one day emulate or even surpass the remarkable career of the man widely regarded as one of the greatest players in the history of the sport.
