Cristiano Ronaldo bursts out laughing as the young son of Al-Nassr team-mate Talisca performs the Portuguese veteran's trademark 'Siuuu' celebration in front of him in the dressing room

Cristiano Ronaldo burst into laughter after a team-mate's son imitated his 'siuuu' celebration, social media footage has revealed.

The Portuguese veteran, 37, moved to Saudi Arabian side Al-Nassr in January after his Manchester United contract was terminated in the wake of a shockingly critical interview with Piers Morgan.

And in a video posted to Instagram, Ronaldo is shown laughing heartily after Anderson Talisca's young child performed his trademark pose in the dressing room.
