Barcelona defender Gerard Pique slammed the referee after his side's 2-1 loss to Athletic Bilbao in the Copa del Rey.
First-half goals from Aritz Aduriz and Inaki Williams saw Bilbao, who would finish with nine men, claim their win at home in the last-16 first leg.
But Barca were denied a penalty to Neymar, while Aduriz was perhaps fortunate not to be sent off by referee Fernandez Borbalan.
Pique was furious and felt his team were perhaps denied two spot-kicks at San Mames on Thursday.
"I think it's a clear penalty [on Neymar]," he said, via Mundo Deportivo.
