Barcelona goalkeeper Marc-Andre ter Stegen called upon his team-mates to raise the quality of their performances late in games after they earned a narrow victory over La Liga strugglers Huesca.
Frenkie de Jong scored a first-half volley that proved decisive at El Alcoraz but Ter Stegen had to be alert to keep Rafa Mir from equalising as the division's bottom club were allowed to attack in the second half.
Ter Stegen acknowledged that Barcelona's display improved on their showing in a 1-1 draw with Eibar last time out in La Liga, but called for more hard work to put the Blaugrana back in contention for a place in the top three.
