Athletic's fans reacted to Setien's yellow card with songs for Barca former coach Valverde.
At 41st minute of the game, Setien protest ostensibly from the technical zone near his bench and Martinez Munuera, the linesman, ran to show him the yellow card. Meanwhile, the San Mames, home of Athletic, was surrounded by the song of "Valverde, what? Valverde, what?" with the same tune dedicated years ago to Llorente after his departure from Athletic.
