Arsenal manager Unai Emery believes their upcoming Europa League game will be the most challenging one in the group.

The Gunners have a tough ask in the first round of the group stages, when they face off against Eintracht Frankfurt away from home.

And Emery is aware not only of the German side's quality, but of the way their home fans can create an impressive atmosphere at the stadium.

Speaking about the game during his pre match press conference, Emery said to reporters: "Yes, we are excited for the competition, we are going to start tomorrow and we are playing opponents who last year played the semi-final against Chelsea and lost on penalties against them.

"To start against them is a tough match for us, but also we are looking to start in the competition.

"We have good feelings in this competition for this season. We played last year in the final, we lost but for us it's a new challenge this year."
