A brilliant goal from Wieke Kaptein handed Chelsea victory on their opening night in what was a promising attacking performance from the Blues.
Summer signing Melvine Malard was bright in her pre-planned 45-minute appearance, while Alyssa Thompson's electric display showcased what she could offer in her second season at Stamford Bridge.
With Ellie Carpenter playing behind Thompson, Chelsea's right side could be a potent weapon as they strive to return to the summit of English football - and, in reality, they ought to have added a couple more goals against Austria Vienna.
However, there were concerns for Sonia Bompastor. Shorn of injured captain Erin Cuthbert and with Keira Walsh substituted early, they ceded control in midfield to the Champions League debutants.
Indeed, Vienna came close on a number of occasions to taking a deserved point, hitting the post and having more shots than their esteemed opponents.
Although Chelsea have only conceded one goal in four matches this season, the fragility on display could cost them against more clinical opponents.
