Arsenal will face Atletico Madrid in the semifinals of the Europa League, while Marseille and Salzburg are paired in the other tie.
The competition is Arsenal's only realistic opportunity to qualify for the Champions League.
Alexandre Lacazette believes winning the Europa League would “save” Arsenal’s season and could lead to Wenger staying on for another year.
“It will save our season because in the Premier League we are not doing well. Winning a cup would be good. It can be the way to keep the manager because he did so much good for the club.”
