In his first game for Barcelona after an all-conquering 2014-15 season, the normally unflappable Lionel Messi was at the centre of a headbutting controversy on Wednesday. 

Barcelona cruised to a 3-0 victory over Serie A side Roma in a pre-season friendly at the Camp Nou but the game grabbed the headlines for Messi’s ugly outburst.

The Argentinian 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 headbutt at Yanga-Mbiwa’s after the Roma defender appeared to nod his head in the direction of the diminutive South American star.

A furious Messi grabbed Yanga-Mbiwa by the throat after clashing with the defender before other players rushed over to intervene.

Messi escaped a red card for the incident however, receiving only a caution from referee Javier Estrada Fernandez. Yanga-Mbiwa was also booked.

The flashpoint represented a rare loss of cool for Messi. The Argentine has never been sent off for Barcelona and has only ever been red-carded once -- on his international debut as a teenager in 2005.

Messi’s anger soon subsided however as moments after the incident, he doubled Barcelona’s lead, making it 2-0 following a superb flowing move involving Luis Suarez, Dani Alves and Neymar, who had scored Barca’s first.
