Unlucky Sunderland Ladies were sunk by an injury-time Georgia Stanway winner at Eppleton CW.
The Lady Black Cats were within seconds of a great - and deserved - result against the English champions when Stanway lashed a 15-yard shot past Anke Preuss.
It was cruel on Melanie Reay's side who performed superbly against their star-studded visitors.
Man City had the first sight at goal when ex-Sunderland defender Demi Stokes shot just wide of Preuss's left stick in the sixth minute.
Jill Scott went wide from the edge of the area soon after, but the home side were giving as good as they got.
Maddie Hill fired over the bar on 17 minutes and Steph Roche was almost in on goal after a bright home move midway through the half.
The Lady Black Cats should have been ahead in the 24th minute only for Roebuck to make a great save with her feet after Roche was in on goal.
A yard either side of the keeper and Melanie Reay's side would have been ahead.
However, the Champions League semi-finalists were always a threat and Tori Williams and Steph Bannon both made vital clearances off the line and Preuss made a good
save at her near post from Niki Parris.
But Sunderland had another brilliant chance when City conceded a corner which Abbey Joice almost stabbled in but Roebuck was able to take.
Preuss came to Sunderland's aid in stoppage time when she made a flying save from a Steph Houghton free-kick.
The Lady Black Cats began the second half with zest, Roche putting her famous left foot to good use from the edgge of the box, her effort fizzing just over.
Her second attempt was less convincing shortly afterwards, but Sunderland were more than matching their illustrious opponents.
Man City made a double change in the 64th minute, bringing on star striker Toni Duggan and Mel Lawley, with Duggan looking good straight away.
Preuss was having a good game in goal for the home side and saved comfortably from Parris 17 minutes from time.
Sunderland continued to defend magnificently and looked set for a deserved point until STANWAY'S late intervention.
