The Sevilla boss is preparing his side to face the Champions League holders in the Uefa Super Cup and is confident they can spring a surprise

The Europa League and Champions League winners meet in Tbilisi on Tuesday, with Barcelona favourites as they head into the new season on the back of last term's treble success.

That said, Sevilla enjoyed a fine campaign of their own and will play in the Champions League this year as a result of their efforts in Europe, with Emery eager to surprise Barca and pick up the season's first silverware.

"We need to find Barcelona's shortcomings, which we know are very few," he said ahead of the game.

"But we know that we have the chance to win a trophy with our first game of the season and that is a big motivation.

"Barcelona are favourites, but we have the advantage of being the surprise. It would be a big boost to our confidence if we were to win."

Sevilla will face Barcelona without new signing Steven N'Zonzi, who has failed to recover from an intestinal problem.

The club also begin the new season without last season's top goalscorer Carlos Bacca, who left the club for AC Milan, though Emery says the team will adapt to his departure.

"There is always substantial work to be done," added the 43-year-old. "In previous years we lost Frederic Kanoute, Dani Alves, Ivan Rakitic and Christian Poulsen and we have always rebuilt.

"We will continue to grow, despite the difficulties and any reconstruction of the squad."
