The Dutchman has criticised the lead match official for sending him off in the final stages of the La Liga clash
Barcelona boss Ronald Koeman blasted match referee Carlos del Cerro Grande after receiving a red card during his side's 0-0 draw with Cadiz, claiming: "In this country, they send you off for nothing!"
Barca extended their recent winless run to three matches in all competitions after a stalemate at Estadio Nuevo Mirandilla on Thursday night.
Frenkie de Jong was sent off midway through the second half for two bookable offences, and Koeman received his marching orders in stoppage time for dissent to compound a miserable night for the Blaugrana.
