Los Rojiblancos coach remained upbeat despite watching his side surrender a 1-0 lead at Camp Nou
The visitors took a surprise lead shortly before half-time through Alberto Botia, but second-half goals from David Villa and Lionel Messi were enough for the league leaders to take the three points.
However, speaking to journalists after the game, the Andalusian outfit's trainer declared that he was happy with the performance his team delivered at Camp Nou.
"I am satisfied," the 41-year-old Spaniard told a post-match press conference.
"A defeat always leaves a bad taste, but we have to look at the positives. We have taken an important step in building something that will help us in the future."
The loss saw Sevilla slip into the bottom half of the table but Emery maintained that there was no need for alarm.
"We had opportunities to draw the game but we just couldn't do the little things well enough," the former Valencia and Spartak Moscow boss added.
Sevilla have dropped back to 12th in La Liga with 32 points from 25 fixtures.
