Cristiano Ronaldo is one of the most famous names on the planet.

But saying it proves a little tricky for the son of the Real Madrid star in a snippet from the upcoming Ronaldo movie, despite it also being his own name.

The scene is an out-take from the upcoming Ronaldo documentary that promises to reveal an intimate portrait of the former Manchester United forward.

It sees Ronaldo Snr becoming increasingly frustrated at Ronaldo Jnr's failed attempts to introduce himself as "Cristiano Ronaldo dos Santos".

Ronaldo Jnr has a reputation for stealing the limelight from his father. At the Fifa Ballon d'Or awards earlier this year the cute youngster endeared himself when he appeared star-struck at spotting his father's great rival Lionel Messi.
