Three second half goals would see Glasgow City lose 3-1 to Celtic at Parkhead.
City would take a first half lead through Lauren Davidson (20) but second half goals from Natasha Flint (60) Claire O'Riordan (76) and Kim Loferski (82) would seal the win for the home side.
Head coach Leanne Ross made just one change from Sunday's win over Hearts with Bea Prades coming in for Mairead Fulton.
A bright start from the away side saw Jenna Clark head just over the bar after neat play had won City an early corner. Priscila Chinchilla latched onto a loose ball shortly after but could only fire wide from just outside the area.
A strong run from Davidson would bring forward the next chance as she ghosted beyond two Celtic defender and fired just wide of the goal.
The home defence would not heed the warning though as Davidson once again darted past the Celtic defence and fired beyond Pamela Tajonar in front of the vocal home crowd.
City would go close again shortly afterwards when neat play between Hayley Lauder and Bea Prades allowed Chinchilla to get a shot on goal.
Amy Gallagher would then get an effort in on goal for the home side but it would not trouble Lee Gibson in the City net. Flint would also try her luck but the ball would sail wide.
More great play from City would then present Chinchilla with a golden opportunity to make it two but the home defence would stand - Amy Muir would then flash a 25-yard drive just wide.
The home would turn up the pressure in the early stages of the second period and Gallagher would be unlucky to fire wide after latching onto a loose ball from a left wing free kick.
City would go close once again though thanks to a lovely floated corner from Hayley Lauder almost being met by Anna Oscarsson but her header sailed agonisingly wide.
And it would come back to haunt City as a long drive from Flint found its way into the corner of the net to level the scores. She would try her luck again from distance seconds later - but it would sail over.
Celtic would then almost take the lead when they latched onto a mistake at the back but Gibson would save superbly before Flint would once again go close with a long range drive that troubled Gibson.
And Celtic would then take the lead with 15 minutes to play as O'Riordan nodded home from a Jacynta cross and a long punt downfield would then release Loforski who would place beyond Gibson to seal the win for the home side.
