Villarreal coach Unai Emery is still fuming after Saturday's defeat to Barcelona.

Emery insists they were robbed of a penalty via an apparent Gerard Pique handball.

He said, "Something that is not in your hands has had an impact on the result because I did not understand the penalty [not whistled for Piqué] and someone has to explain us, I have the feeling that Villarreal ... I do not feel respect, because they have spent quite a few episodes here this season.

"We deserve an explanation from someone because if the referee doesn't see it, why the VAR does not say anything?

"The penalty [from Piqué] is a ball that is going to goal, and Piqué raises his hand and diverts it."
