Mariona Caldentey scored a late penalty to send Arsenal through to the Women's Champions League quarter-finals as Group C winners with a 3-2 victory over Bayern Munich.
Renee Slegers' side knew three points would see them leapfrog Bayern and top the group, giving them a better seeding in the draw for the last eight.
The Gunners took a seventh-minute lead at Meadow Park - the fixture moved from the Emirates Stadium because of a clash with the men's Carabao Cup quarter-final - through Glodis Perla Viggosdottir's own goal.
Magdalena Eriksson equalised for Bayern before the break when she smashed home at a corner and then put her side ahead in the second half, stretching to turn in Giulia Gwinn's cross.

However, Bayern's lead lasted less than 60 seconds as Alessia Russo volleyed in from a corner.
Arsenal needed a winner and were given a chance when Tuva Hansen handled an effort from Caldentey with four minutes remaining. Caldentey stepped up to the spot and coolly dispatched the penalty to extend Arsenal's unbeaten run to 11 matches across all competitions.
