Barcelona won the Joan Gamper Trophy after defeating AS Roma 3-0 at Camp Nou on Wednesday night. Lionel Messi made his preseason debut, scoring a goal in the process. Everything was going well, until Messi went absolutely nuts:
Roma defender Mapou Yanga-Mbiwa fouled Messi, then clearly said something and leaned his head in to force a retaliation, which happened as the Blaugrana star and captain in this match delivered a clear headbutt. That would have been fine, but things got worse when Messi grabbed Yanga-Mbiwa's throat and shoved him. Since it's a friendly, the referee decided to let it go and nobody got sent off.
