Chelsea have been paired with Dynamo Kiev in the last-16 of the Europa League, while Arsenal have been drawn to face French side Rennes.
The Blues eased though the first knockout round of the competition thanks to a 5-1 aggregate success over Malmo - with Chelsea looking to repeat their Europa League triumph of 2013 - when they defeated Benfica 2-1 in the final in Amsterdam.
Their only previous meetings with Dynamo came in the group stage of the Champions League in 2015, when the clash in Ukraine ended goalless, before a late goal from Willian earned the Blues a 2-1 victory at Stamford Bridge.
Meanwhile, the Gunners - who have never previously faced Rennes in a competitive fixture - eased past BATE Borisov in the last-32, winning 3-0 in their home second leg after suffering a shock 1-0 reverse in the first match in Belarus.
Rennes, meanwhile, came out on top in a thrilling tie with Real Betis, winning the second leg 3-1 in Spain after the first game in France had ended in a 3-3 draw.
Elsewhere, Inter Milan have been drawn against Eintracht Frankfurt, while record five-time winners of the competition Sevilla have been paired with Slavia Prague.
