Lionel Messi head-butts Mapou in fit of anger

It's not usual to see Lionel Messi react like he did in the 33rd minute of Barcelona's clash with Roma. The Barcelona forward clashed heads with defender Mapou, before grabbing the player by the throat. 

The referee had stopped the play for offside and as Messi turned to run back he was provoked by the Roma player. Minutes before, Mapou had suffered a nutmeg from Messi.

Fortunately for Barcelona, Messi was not sent off for his head-butt and instead was only given the yellow card, along with Mapou. Messi went on to score as Barcelona won the Joan Gamper Trophy with a 3-0 win.
