Alexis Sanchez struck in the last minute of the first half, to ensure that Arsenal will play in the Champions League proper, for the 17th consecutive season.
The Chilean striker who cost the Gunners £32m, latched onto a Mesut Ozil pass and slotted the home. Mathieu Debuchy was sent off in the second half of the game, for a second bookable offence and Arsene Wenger’s men had to battle through for over 15 minutes to win the tie.
Arsenal and other qualifiers from yesternight, like Atletic Bilbao and Bayer Leverkusen, will go into the draws for the group stages on Thursday by 4.45pm.
