The two Premier League clubs meet in Baku for the final with commentary live on talkSPORT
Not only will it be a first piece of silverware for the manager but also mean a coveted Champions League final place.
The Gunners finished outside the top four in the Premier League but have a second chance of getting into next season’s elite European competition.
They must beat Chelsea in the final in Baku, with commentary live on talkSPORT, to seal that place.
Here at talkSPORT.com we have taken a look at how Arsenal could line-up for the final tonight.
There are still question marks over who will play in goal for the Gunners on Wednesday.
Petr Cech could be in for a final swansong before his retirement at the end of the season and has been their goalkeeper in the Europa League this season.
He could decide to go with Bernd Leno who has been their league keeper and deny Cech the chance to close out his career against his former club.
Speaking in his pre-match press conference on Tuesday, Emery said: “The first XI for tomorrow, I’m going to see tomorrow.
“Cech is a great man, a great professional, it is amazing his behaviour and final year with us.
“I want to do something important with him in the last moment of your career, playing or not playing.
“He deserves trust in him, his career says to us he is a gentleman. He can start or cannot start, I am going to decide.
“How can we not believe in him?”
Emery is likely to go five at the back with Sead Kolasinac and Ainsley Maitland-Niles to be used as the wing-backs.
Sokratis Papastathopoulos, Laurent Koscielny and Nacho Monreal should line-up as the central defenders.
Lucas Torreira and Granit Xhaka will be used in front of the defence with Mesut Ozil in the more advanced attacking role.
Pierre-Emerick Aubameyang and Alexandre Lacazette have formed a fantastic partnership this season and have 50 goals between them and will be a danger for the Chelsea defence.
