Barcelona coach Luis Enrique was visibly frustrated when asked questions about Gerard Pique's latest social media posts.

Pique is facing investigation after posts about Real Madrid's win at Villarreal on Sunday.

"I have nothing to say about the referees, I have already spoken this season and the previous ones, you already know my opinion and I will not change it, the rest I am no longer interested," snapped Enrique.

A reporter then asked: "Are you proud of all your players because of their behavior towards the referees, like (Zinedine) Zidane says about theirs?"

"I have nothing to say," Luis Enrique replied.
