The draw for the Europa League last 32 has been made at UEFA HQ in Nyon, Switzerland following the conclusion of the group stage of the continent's secondary competition last week.
As per the usual procedure at this stage of the competition, the 12 group winners and 12 group runners-up were joined by the eight third place teams from the Champions League, split evenly between the seeded and unseeded sides depending on their Champions League record.
Teams from the same country could not be drawn together, while teams that qualified from the same Europa League group were also kept apart.
Playing in the Europa League for the first time since reaching the UEFA Cup final in 2000, Arsenal will now face Swedish club Ostersund after successfully navigating the group stage.
With the best record from the group stage with 16 points from their six games, Russia's Zenit St Petersburg have been paired with Celtic.
As far as the high profile Champions League dropouts are concerned, Borussia Dortmund must play a tough Atalanta side (pictured below), while Atletico Madrid were drawn against Copenhagen, and Napoli against fellow Champions League side RB Leipzig.
