Angry Messi loses his cool

Lionel Messi was at the center of a head-butting controversy on Wednesday as Barcelona cruised to a 3-0 victory over Serie A side Roma in a preseason friendly at Camp Nou.

The Argentine superstar, renowned for rarely losing his cool despite regularly being the target of brutal tackling, reacted angrily during a confrontation with Roma's French international Mapou Yanga-Mbiwa.

Footage of the first-half incident showed Messi aiming a head-butt at Yanga-Mbiwa's after the Roma defender appeared to nod his head in the direction of the diminutive South American star.
