Barcelona striker Luis Suarez has claimed that the Catalan side were frustrated with referee Carlos del Cerro Grande's performance in Sunday's 3-1 win over Eibar.

Barca centre-back Javier Mascherano was handed a red card in the latter stages of the La Liga contest after reportedly insulting the assistant referee's mother following a late challenge.

Suarez has said that he does not know what occurred in relation to the Mascherano red, but has revealed that his teammates felt Eibar were given a free pass to make a number of late challenges without further punishment.

"I don't know what happened [regarding Javier Mascherano's red card]. We got the feeling that [Eibar] were fouling us but weren't being shown any cards," Suarez told reporters.

Suarez scored a hat-trick in the home victory for the Catalans to ensure that they moved level on points with Real Madrid in the La Liga table.
