During Barcelona's shock 1-0 defeat to Espanyol in the first leg of the Copa del Rey quarter-finals, the chant "F**king Barca, f**king Barca, eh, eh" was repeated eleven times in the 'Gol Cornellá' sector by some passionate home fans.
However, in the 24th and 76th minutes of the game the insults were aimed at the Spanish defender Pique with some fans chanting "Pique a**hole, Shakira has a p**is, your son is Wakaso's and you are a f**got".
The Spanish league added: "At various times, and after a number of renditions of the songs previously mentioned, the local club issued a public address asking the fans not to make offensive chants towards the players or the rival team."
La Liga praised the majority of the Espanyol fans, saying: "The rest of the fans in the stadium displayed at all times appropriate behaviour during the course of the game."
Pique signed a contract extension with the Spanish giants on Thursday, keeping him in Barcelona till 2022.
