Video: Lionel Messi headbutts as tempers flare during Barcelona's win over Roma

Barcelona: Lionel Messi was at the centre of a headbutting controversy on Wednesday as Barcelona cruised to a 3-0 victory over Serie A side Roma in a pre-season friendly at the Camp Nou.

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.

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.

Ivan Rakitic made it 3-0 in the second half with a long range strike as Barcelona completed a routine win.
