Barcelona defender Gerard Pique could be punished for his recent social media use after La Liga's "anti-violence committee" has reviewed his actions and sent a case to its discipline committee.

Pique has riled La Liga rivals Real Madrid with his use of Twitter, while he has also spoke controversially in a postgame TV interview after last week's bad-tempered Copa del Rey match with neighbours Espanyol.

When it was first reported last week that that Spanish football authorities were investigating his behaviour, the Blaugrana centre-back reacted by posting a message including a video which appeared to show Espanyol fans abusing both his wife Shakira and son Milan during the recent La Liga fixture at Espanyol's Cornella El-Prat.
