Sevilla manager Luis Garcia Plaza has launched a scathing attack on the officiating following his side's 4-1 loss to Real Madrid, claiming the referee "robbed" his team of a fair chance. The angry coach insisted that Arda Guler should have been sent off for an off-the-ball incident early in the first half, and believes a conspiracy may be at play to ensure Los Blancos remain in peak condition for the upcoming El Clasico showdown
