Chelsea were the first British team drawn and the 2013 Europa League winners will face Malmo of Sweden.
Celtic, who advanced despite losing their final group game at home to Red Bull Salzburg on Thursday, were paired with Valencia – who dropped down from the Champions League having beaten Manchester United in the group stage.
Arsenal will play the second leg of their Europa League round-of-32 clash at the Emirates Stadium on Wednesday, February 20 2019, with the game set to kick off at 17:00 – UEFA has confirmed.
Both the Gunners and London rivals Chelsea topped their respective groups and will therefore play their second legs at home – with UEFA rules stipulating the pair cannot play in the city on the same night.
Arsenal will therefore be the team whose fixture is brought forward with UEFA confirming to Press Association Sport that, as FA Cup winners, Chelsea are given priority.
The situation is clouded further as the tie cannot clash with any Champions League fixtures played on the same day, meaning Unai Emery’s side will kick-off at 17:00.
