The banner targeting Gerard Pique's wife during the Copa del Rey second-leg was indicative of a "macho culture", according to mayor Ada Colau.
Barcelona city mayor Ada Colau has criticised a derogatory banner held up by Espanyol fans targeting the popstar partner of Gerard Pique during Wednesday's Copa del Rey match.
Barcelona prevailed 2-0 thanks to a Munir brace at Cornella El Prat, the home of its city rival, to ease to a 6-1 aggregate win in what was often a bad-tempered last-16 tie.
Pique has been the target of abuse from Espanyol previously and he mocked the club's supporters for not being able to fill the ground following Barca's 4-1 first-leg triumph at Camp Nou.
