Unai Emery acknowledged the gap between Aston Villa and Barcelona after his side's defeat, insisting there were positives to take but admitting his team must improve to compete at the Catalan club's level.
Barcelona extended their strong start to the season with a victory over Villa, taking their record to 13 wins from 15 matches across all competitions.
Emery praised his players' effort but highlighted the need for greater consistency and quality to bridge the distance to Europe's elite.
