An exquisitely-taken goal from Fran Kirby was enough to carry Chelsea Ladies to the Women's Champions League last-16, despite a nervy 2-1 defeat to Bayern Munich.
With her side holding a slim advantage from the first leg of the last-32 tie, Chelsea boss Emma Hayes stuck with the same line-up that earned a 1-0 win at AFC Wimbledon's Kingsmeadow stadium a week earlier for the trip to Germany.
Quarter-finalists last season, Bayern made one change as Mandy Islacker - who scored the winner for Frankfurt in 2015 - replaced Melanie Leupolz, and it was Islacker who handed the Blues their first test when she volleyed over after Hedvig Lindahl's save after 20 minutes.
Die Roten were forced to defence well as their visitors hit them with a barrage of attempts as the first half progressed; Ramona Bachmann, Katie Chapman and Magdalena Eriksson all hit thunderous shots at Manuela Zinsberger, while Maria Thorisdottir nodded a corner wide.
It was the hosts who started the second half in a brighter fashion and Leonie Maier shot wide following a goalmouth scramble, but up popped Kirby on the hour mark to settle the nerves of the Londoners' sizeable away support.
As Bayern squandered possession the Blues capitalised; Bachmann squared for Kirby in the middle of the park, who dragged the ball out wide and clipped an expert finish over Zinsberger into the far corner.
With three goals now required for Bayern to advance, the Germans upped the tempo of their game and were rewarded with one of those goals when Fridolina Rolfo poked home a corner from close range with 76 minutes on the clock
The same situation occurred seven minutes later. Lindahl saved a shot after an initial corner wasn't cleared, but Lucie Vonkova was on hand to bundle the ball home and set up a nervy finish.
A third looked on the cards when Lineth Beerensteyn got the better of Millie Bright on the left and located Dominika Skorvankova, though the close-range effort was deflected wide amidst a huge sigh of relief from the Blues camp.
Seven minutes of stoppage time were added, but Chelsea held on to advance on away goals. Wild celebrations ensued and the west Londoners find themselves in the hat for next week's draw.
