BARCELONA (Reuters) - Barcelona coach Ernesto Valverde said fans can protest if they wish but must remain respectful during Wednesday's La Liga clash with Real Madrid, which is set to be a highly-politicised encounter between Spain's biggest rivals.
'El Clasico' has always been fraught with tension -- Luis Figo, who left Barcelona for Real Madrid, famously had a pig's head thrown at him in one match in 2002 -- and anger about the central government's handling of the region's independence drive is expected to be felt in the stands.
