However, Emery said Arsenal would stick to their guns against Frankfurt and look to improve on Sunday’s performance by taking a leaf out of their first-half display against Watford when they went 2-0 up.
“The first analysis is on how we can improve and recover our confidence, starting and controlling the match,” Emery added. “Sunday we struggled more than we wanted and also we made some mistakes and conceded some goals.
“We want to control every game with the ball, with positioning. We did on Sunday in the first half.”
Frankfurt reached the semi-finals last season, where they were beaten by eventual champions Chelsea and Emery – who has won the Europa League three times with Sevilla but lost last year’s final – said he was looking forward to a “new challenge” this season.
“Usually Eintracht are doing high pressing,” Emery said. “Some mistakes we made on Sunday we need to improve. Tomorrow is another challenge to show how we can improve.
“Last year Frankfurt played in the same semi-final as Chelsea. To start tomorrow with them is a tough match.
“We have good feelings for the competition in this season. We lost the final last season but this is a new challenge for us.”
Kolasinac: Attack was difficult mentally
Arsenal defender Sead Kolasinac spoke for the first time about how he and Ozil had been the target of gang attacks on the eve of the season.
Kolasinac jumped out of a vehicle to confront masked aggressors in the summer, who had pulled alongside them on mopeds, while a separate incident led to two men being charged with a public order offence outside Ozil’s house.
“About what happened I don’t want to talk about it in details,” he said.
“It’s happened and it’s something that belongs to the past. The same with Mesut. We are back and we focus on our job and team. We have a very important match ahead here in Frankfurt.
