The match, originally scheduled for 20.00 GMT (21.00 CET) at Signal Iduna Park, will now kick off at 20.15 GMT (21.15 CET). Both teams are competing in a play-off for a place in the Round of 16, with the second leg set for February 25.
Atalanta will be missing Charles De Ketelaere and Giacomo Raspadori, both out for at least a month with injuries, but Gianluca Scamacca returns to the starting lineup.
