Ousmane Dembele has scored seven goals for Barcelona this season
Ousmane Dembele scored the only goal as Barcelona beat in-form Real Sociedad to book their place in the Copa del Rey semi-finals.
The visitors, who had won their previous nine games, had Brais Mendez sent off in the first half for a dangerous tackle on Sergio Busquets.
Dembele settled the tie when he ran onto Jules Kounde's ball down the right wing before hammering in from an angle.
Gavi almost put the game beyond doubt but hit the bar.
