Should OM win past RB Salzburg, they will earn a place in the UEFA Europa League final at the Groupama Stadium in Lyon, taking on the victor of the other semi-final, between Arsenal and Atletico Madrid.
The first legs will be played on Thursday, 26 April, and the return duels on May 3.
The match-ups were decided on Friday afternoon.
"Perhaps in Arsenal's favour is that Atletico do play a high intensity style that is not dissimilar to Premier League clubs, so Arsenal won't find it too hard to prepare". BT Sport will also have a live stream of the draw.
Striker Alexandre Lacazette has urged Arsenal to go on and win the competition to improve Wenger's prospects.
The Gunners' 2-2 draw against CSKA Moscow in Russian Federation on Thursday night gave them a 6-3 aggregate win to put them within touching distance of next month's final in Lyon. "I came to Arsenal because I want to win trophies". "I really want to be in the final to play in front of my family and friends", he said. Arsenal, who have never won the Europa League or UEFA Cup, will face the tournament favourites Atletico Madrid in a semi-final clash which both sides would have preferred to avoid.
Asked about the significance of the Europa League and Wenger's own future, Lacazette replied: "It will save our season".
Arsenal are in sixth spot in the Premier League table and 13 points adrift of Liverpool FC and Tottenham Hotspur. Unfortunately some players have to play all the games. "So we play in it with enthusiasm", he added. It is mentally maybe tougher than physically'.
