Arsenal will face off against Swedish side Ostersunds in the last-32 of the Europa League.
The Gunners avoided some top opposition in their draw – but will come up against an English manager in Graham Potter.
Arsenal’s performances against Cologne, Red Star Belgrade and BATE Borisov ensured that they secured top spot with a game to spare.
Despite playing a slightly weakened side in every game, Arsene Wenger’s men only lost one game during the group stages.
Celtic, meanwhile, have been drawn against Roberto Mancini’s Zenit St Petersburg.
The two legs of the last-32 matches will take place on February 15 and February 22.
Teams will then return for the last-16 a couple of weeks later.
