INIGO MARTINEZ got into an angry spat with a young football supporter in the middle of the road.
The Barcelona star, 32, stopped his black Range Rover in the street before climbing out of the car to confront the child in shocking scenes.
Dressed in a white t-shirt, grey shorts and white trainers, he walked up to the young fan, who also approached him.
And the centre-back then unleashed an angry rant directly in the supporter's face, pointing and raising his voice furiously seemingly frustrated by the treatment or abuse from the youngster.
It was unclear what sparked the incident.
Martinez spoke in Spanish for approximately 20 seconds but did not appear to make any physical contact.
